I bet there are tons of seemingly "conflict of interest" in companies boards. In fact, being major shareholder qualifies (but not sufficiently) for the board. Jobs was Disney's board member after Pixar's acquisition. You could argues Apple is now a competitor to Disney. So what? If a competitor acquires enough control of a company what's wrong?
Steve died 8 years before Apple Tv+.
He would have probably left the Disney board by now. Or Apple might have invested in DIS.
It seems hard to imagine a board member that is involved in another tech business not having a conceivable conflict of interests. LLMs are on a course to disrupt pretty much all forms of knowledge work after all. Also big implications for hardware manufacturing and supply chains.
