We hate on Nintendo and Rockstar for DCMA’ing free/open source mods/project, not paid ones. If you’re charging money for a tool, you’re running a business. If your business involves another business’s product, like with AI training or freaking phone cases, legal demands like this become a fair part of doing business.

Granted there is still a power disparity to recognize, even if the guy is a douche. But it’s not unfair in the way DCMA’ing things made freely for the community is unfair.
