Neither GPL nor MIT (or anything else) protects you against this.
(EDIT) scenario: I make a browser extension and release v1 under GPL, it becomes popular and I sell it to an adtech company. They can do whatever they want with v2.
I’m not good at car maintenance but I would benefit from an environment where schematics are open and cars are easy to maintain by everyone: there would be more knowledge around it, more garages for me to choose from, etc.
I'm most familiar with the "right to repair" situation with John Deere, which occasionally pops up on HN. The spirit of someone who releases something under GPL seems the opposite of that?
Like, "we don't like copyright, but since you insist on enforcing it and we can't do anything against it, we will invent a clever way to use your own rules against you".
They are literally stealing from open source, but it's the original license that is the issue?
