but because of “fuck you” move
The guy removed the attribution because he is being harassed.
The 'fuck you' move is the people harassing an open source dev. Those people are the source of the bad behavior, not the guy who volunteers his time maintaining an open source project for everyone to use.
The anti-AI crowd is toxic and need to fuck off. It's one thing to have an opinion, it's another thing to harass volunteers because they're using tools that the crowd has a hateboner for.
