Unless there changes something Fundamentaly about developing games, that sets the barrier to start up with a game WAY higher than it currently is. You should take a look around before you make Statements like "it feels like they going extinct".
The amount of people who Study in the IT field is crazy, sure not all of them have the end goal of developing Adult games, but if you look at the market, ever since there is a flood of people able to do certain jobs. Companies more and more cherry pick, and on top of that, there is not an unlimited amount of jobs to be had in the first place. So the result is that you end up with tons of people with a basic know how, and without a job. Im not saying that this is the case for all Adult Game devs, or even for the majority. But whether you are adult game dev, by choice from the get go, or if you slided into that role and now live with it because it pays your bills. Dont be so naive to think that the supply on Devs is running low.
Also that Argument with PR, holy crap, if i am a dev who wants to abuse/exploit patreon to milk as much money out of it as possible, with the least effort. Why on earth would i give two fucks about whats better PR? Especialy given the fact that people like you, openly admit that they heared "im ill" one to many times. Then i'd rather say "I'll take a break foor who knows how long, but ill be back" that way i can keep on running my Patreon and even if thats thin ice, argue that i kept my Patreon running because my plan was to come back, and i have something special for my loyal fans.
Im not saying people dont exploit it, they sure do. But you also cant start a Sentence with "I don't want to be accusing anyone, but". And then follow this by a couple of lines accusing people of stuff...cmon man
