Unfortunately true.
I'm just differentiating between the legal correctness and personal opinion/viewpoints on the matter.
Regardless of whether you are legally correct or not isn't really the crux of the issue for me, heck maybe Jensen doesn't even care about a billion given everything's he's minting (who knows though).
I was only talking from personal standing, in your stated cases or if I was in this position (I made some assumptions regarding the case), it would be a breaches of good faith and I would find it hard to trust them in a partnership ever again.
Only my POV, maybe the folks at the B level don't care about this as much since they are starting to fling Ts around. I can see how some people wouldn't really care, i.e. treating them as a freelancer and main objective is getting something done, but on a personal basis probably wouldn't trust them (say on personal matters that are company defining).
