Honestly, it's basically an obsession with people "stealing" by the developer. I'm not going to go into any pro / against debates on piracy here, but the developer pretty clearly falls onto the "piracy is theft, and if there's no pirated version I'll get more sales" frame of mind.
Yes. I think this is clearly a behavior developer think is justified. I wont claim it is not, because in his mind piracy is clearly a blatant disturbance, and is trying to control the release of game to non-patreons at first, then judged it impossible and is now with holding the compeleted content to himself.
I won't say whether it is right behaviour or not but one thing I will say is he himself is reacting in exact way you would expect a pirate to behave.
I personally find this entertaining show.
Game is fun yea but that's it there are various other games and other sources of joy for me. Basically hentai and porn industry is de-facto immortal now.
