We say "stealing ideas" but nothing is actually being physically removed from anyone else. What you're talking about is "copyright infringement" in legalese, which you'll notice doesn't really refer to any kind of "taking" in its wording.

Sorry to go off-topic. And it is off-topic, since as I said before, I'm cool with all of this, especially if the name gets changed.
Anyway "RoB 2.1" would be a bad idea even if you were
