That‘s the thing with huge, shitty corporations. Even when they know they‘re absolutely in the wrong, they can still go after the small fishes and make their lives hell.
To give another example, LEGO has been flooding small toy sellers in Germany with cease and desist letters for selling sets from competitors that might look like knock-offs to some, but are perfectly legal because LEGO does not own the brick system. And of course they would never go after Amazon for doing the exact same. Only small sellers that are ruined if they can‘t scrape the money together for a proper legal defense.
