I'm actually not too worried about piracy, on the contrary, but for example if someone takes my game and SELLS it on google play.
Viewing post in What license I have to use for my game?
You are aware of the nature of your own game, are you? Not even you could publish it on google play.
Someone could steal your stuff an publish it on Steam maybe. Or other platforms that allow it. But that is the same for every game. Respectable platforms will remove plagiarisms and copyright violations and the like. Even Itch. Though on itch it usually is malware and not trying to actually sell the copied game.
I think there is a sweet spot for the criminals. A game popular enough to copy and sell it, but not popular enough that it gets banned immediatly. Games in the nieche you make barely ever reach that sweet spot, let alone overcome it. Not only is it adult, but also ai. And it is not finished. There are not many places for such games. Actually, I am not even aware of any place except itch. One might count patreon and the like, but those have no game catalogue and library. There is some small publishers that do direct marketing and have their own shop system.
