I know that @Vortico has done due diligence with a lawyer about licensing issue via a via Rack.
So I - without really understanding it all - will not worry about the things he says not to worry about.
The thing about FSF is that Stallman had quixotic, absolutist ideas about free software that were challenging to adapt to to the real world. They are polemicists, not your legal advisors.
He’s also kinda cancelled these days, though I guess he’s back on the FSF. But the less said about that the better.
