There are a lot of reasons to not communicate in that situation. People don't like to admit to giving up on things. People don't like admitting to themselves that they have given up on things. Also, I have only seen a single digit number of patreon accounts where the creator actually said they were quitting/giving up on their project. Meanwhile I can point to many dozens of projects that have been inactive for years where the last post says that they will be releasing an update in a few days/weeks. I've been following Vren's work since early in the original Lab Rat's development, so I am probably more aware of his update consistency than you are. Go back and look at the last few months of vren's patreon. The posts grew less and less frequent. The last thing he did was sort of make the project open source. To me those two things seems to vaguely resemble evidence of waning interest or lost motivation, but I guess not to you.
I feel like you are taking the abandonment of this game personally. As I have said in older posts, Vren said he started on LR2 as a hobby and way to learn coding. Contrary to that, the last few months of communication from Vren had been doing almost nothing but porting images for hours at a time. I guess that if you need to convince yourself that the only way the game would be abandoned is if Vren had died, then you can ignore all the other possible explanations and do so. In the grand scheme of things what happened doesn't matter unless he decides to come back to game development some day.
I completely agree with you. I too believe that Vren has gone off on its own.
I know the code and features of the game pretty well, and I can safely say that the game is a dead end.
The fact is that the game was intended to be a sandbox game. But the chosen code concept has two major flaws:
1. The complexity of adding graphical content grows exponentially. In order to add a new pose you need to add not only 18 body pictures (3 body types x 3 skin tones x pregnancy status), but also about 40 (13 types x 3 skin tones) face pictures and several dozens (if not more than a hundred - pictures of clothes and accessories), ah, and hairstyles - about 20 pieces.
2. Difficulty of adding (or changing) programme code for already started games. At first glance, the game logic based on Action objects is revolutionary in relation to most Ren'Py games. It seems to be enough, without changing any script files, to add a file with define object Action and a block of Ren'Py code with the appropriate label and we will get a new event in the game, even started. But Vren did not fully realise this possibility. All objects are saved with the game - even menu items. And it is impossible to add an action, a menu item, a new room, a personality type, a job, eventually a trait serum to a started game.
I too have watched the evolution of LabRats2, and I confirm that most of Vren's work was spent adding pictures to the game.
And if you need to add a logic change, there was no solution for the sandbox other than "let's burn old saves". And that, I think, annoyed subscribers. However, there is always the option to "hook" one event into another, and add the necessary objects to the started game, but it's not that easy, and it's not really clean for the sandbox concept.
And I believe that such difficulties no less than an accident could have caused him to leave the project.
And if someone likes to harp on the Ukrainian option, I believe this forum is out of politics, and it's against the rules.
