The business model is entirely up to the developer. Patreon has never been a tip jar (except in the very early days) no matter how much it tries to brainwash people into thinking that is the case, but this isn't about Patreon (or any platform), this is about developers in general.
Should developers hate F95 for being a piracy website? It gives them free advertising just like any other pirate website. There are pros and cons, but free advertising will always beat power advertising because it doesn't require the creator to sell their heart, soul and passion to a company in addition to their rights and privileges or most of it. It's a rather large community with over 5 million accounts and at least 100k fairly active. I'd compare it to someone asking if artists should hate E-Hentai when Tenboro did the same as Sam here and added banners to support the artists. Unfortunately, those were company banners, which is why I appreciate it when F95 automates "Support Anonymous" instead of using, say, "Support Steam" or "Support Patreon". This backfired into encouraging more hypocritical DMCAs than actual advertising.
Should developers hate F95 because people are self-entitled? This doesn't just happen on F95. Go check any community. Be a greedy developer, milk your audience, destroy your own humanity and you'll grow a massive fanbase brainwashing others into doing the same if you're shameless enough to do this. And because bias is bad, there is the other end of the spectrum: cater to your audience's needs and whims, overwork yourself, don't ask for anything, do it for free, place all bets on passion and efforts... and end up completely and utterly depressed with a ruined life and no support whatsoever since depressed people usually aren't very productive and the pity card only really works for the ones who have zero empathy and do not deserve to be called human. In both cases, a large portion of the audience will be self-entitled and will go bonkers the instant the developer, artist, musician, writer, and so on fails to deliver. Large but not 100%. Minorities matter even if they are powerless. The thing is that's how most people are, not any community's fault. Companies encourage that mindset. If you are human, prove it and don't get baited into falling for it, either as a patron or as a creator ready to do anything to get attention, power and money.
There are pros and cons to all plans like Anne pointed out, but for developers who prefer to go with - I won't use that word, they're no longer one, so I'm using the actual phrasing - crowdfunding social platforms, the timegate approach works nicely if people are tolerant and patient. Patience is a virtue and it is extremely rare in 2021 due to how easy it is to get hold of just about anything in first world countries with the average lifestyle, pandemic or not. (People don't even care about the pandemic, but people have absurd priorities in 2021, or maybe they're just narcissists and selfish when many of us end up as misfits as we have failed to adapt and grow into space monkeys. It's a whole other beast, really.)
Then there's the get it for free, pay whatever you want, whenever you want if you like it approach that only works for games as far as I am aware. Itch. Name another platform that gives you an option to pick between 0%, 10% and 30% of your sales (completely free products included in the term, but the money received will be seen as income, not as a donation) and defaults to 0%. With the current trends, it's increasingly worrying to see free developers who hand out 30% to itch and developers selling for big bucks and with the setting at 0% but they've probably planned it. It's covered in their FAQ. This is the closest approach to the 70s and 80s shareware trends for the older folks out there. Free demos used to be almost entire games and were so absurdly cheap it felt bad if you were not able to support the developer (not because you are poor because 99% of the time, that's a lie - be honest, poor people won't exactly be tweeting and liveblogging on something they aren't supposed to have - but because, and there's no shame about admitting to it, you may not have access to a payment method, you may be rightfully anxious about a proper way to approach possible direct payment methods or you may just be unable to do it for any other reason that isn't "I don't want to").
And then there's what Anne mentioned. Leaks will happen, you can't prevent leaks - you can only mitigate them, usually by being fair so they don't happen. Even big tech companies can't with their supposedly unbreakable technology and security when all it takes is a massive database dump with 2 billion people to land at some point for people to notice. Don't expect anything to be safe, secure, private, and most importantly deleted. Nothing ever is deleted from the Internet itself, only removed and made extremely hard to access if it is something super sensitive - but never impossible. There is no digital sledgehammer or ion cannon in the HackNet. You can zerofill and randomize all you want, encrypt with as many layers of encryption and obfuscation, the original data was available to you. Nobody even needs to physically or psychologically torture or blackmail a content creator to get what they want: all it takes is a single misstep for a leak to happen. Mistakes are human by design, even deities make mistakes - if you believe in a deity-based cult or religion, we are the living (or dead, if only...) proof of this.
If developers don't want to end up depressed or don't want to end up joining the current paypig trends, they should be themselves, create something they love (Patreon, 2013, aged like milk) and be passionate about doing it for themselves and, by extension, for others. Work goals ("promises") are non-binding, deadlines don't exist. Don't give deadlines if you can't meet them. You don't have to meet them. Don't blog with your audience about your real life (unless it genuinely affected your work, then all you need if your intent was to build a platform for your work, nobody cares except for "simps" and sharing private, sensitive, personal information is a very bad idea no matter how much attention and money you get from it. Use the platform to give progress reports when you can. If you do it right, that will be often, and you will be providing information that is entirely related to what you are making. If people don't care, then they didn't come here for your work. It's that simple.
Stick to a regular schedule, don't work on 100 things when you can hardly focus on one and be glad you have a real tip jar at hand somewhere should someone want to throw a buck or two every now and then. If you are working on something big that requires investment, then keep in mind the platform is only here to act as a legal middleman and advertising. Advertisement can backfire and proxy lawsuits are rather overrated unless your work is highly contentious (but if it is, the platform won't allow it in the first place, so it's a non-issue). Kickstarters using double-standard payment processors can destroy you, don't fall for it. Real and honest developers rarely make a profit but if they value their humanity and working on their beloved project (or projects, if properly planned) didn't destroy their health or sanity (or both), then breaking even is more than enough.
tldr: Piracy happens to everyone. Deal with it.
Since you're most likely doing it too, don't judge others when it happens to you, nobody is special.
