Maybe this developer should to die? It will be act of justice and note for other developers. Like Pavel Durov said lately - "You should respect your users". I think Team Borsch don't.
And I have another point: I heard developer buy some subscribe account to make vision of success. Some people see user's count and subscribe too. Money for fake account service returning with tax.
Well if you really think this developer should 'die' or just stop making games - Then I don't see your point in even sitting in this thread and discussing things - Since you don't care, there are plenty of other developers out there to follow instead.
With hentai games and patreon, you don't get more patreons because you just have a high count of current patreons. That makes absolutely no sense.
You get increase in patreons because you deliver something good, different, or unique. That also include very popular genres like incest, bestiality and other fetishes.
In terms of Team Borsch - The deliver really good 2d artwork, and a very interesting story that goes along side it.
They have between 1000-4000$ per month. That does not make them especially big/popular or well paid.
