"but of an arse" is pretty generous for behavior that would cost him his job today.
Look at what the U.S. President has and continues to do, and he still has his job, and a much more important and public one too.
Politics aside, Jobs' turnaround of Apple into the most valuable company in the world (for awhile, recently) would have ensured he remained at the helm for as long as he wanted.
The no-poaching collusion between Apple et al probably cost Apple a nine-figure sum to settle (I'm not sure what the exact breakdown between the defendants was): https://en.wikipedia.org/wiki/High-Tech_Employee_Antitrust_L...
Both of these were quite serious issues, in my opinion.
