People will pirate no matter what and for various reasons. That’s fine. Gloating about it publicly is just weird to me though.
What would make it easier to donate for things which have been freely distributed as torrents? Some links in a bundled text file?
For indi-devs having a “donate” option on their page might be good for both people that maybe pirated but liked it enough to send some amount (even if not the full price). And could be a random source of money to off-set some of the pirated copies from people that just decide they wanted to show additional support for the efforts of the devs.
Lots of fans are willing to leave donations especially if the devs are at risk of shutting down or some other hardships. So long as the donation options only go to the devs/creators or their specific studio/company and not to some larger entity/publisher. Store fronts like itch.io allowing devs to have both an official front to allow safe free copies along with the normal price and “pay what you want” stuff is also nice.
