I'm on Team Sam, lol.
I know not all (or even many) of the fact are out, but it seems to me that Oliva propped the guy up, and now thinks it's unfair that he has "a name" in the buisness. Look, if you train a guy you know he might not stick around, you don't own them indefinately. You can't sue someone for the general know-how they learn on a job, only for "confidential information." If Sam was copying the Oliva V for his first release, obviosuly that would be different.
From Oliva's perspective, they probably feel they created a monster and it got out of control. But that's often what happens when you make monsters. Take your lumps, Jose.
