You wrote that he was probably more ignorant than ill-intentioned. That implies good intentions or no intentions.
The intentional asshole makes good decisions for the company, think Bill Gates in the 90s. These days he's shown that that was business, now with the Foundation he's choosing to not be that guy. TK does not appear capable of a change like that.
I think being an asshole and being demanding can also get really misconstrued, lots of people who have worked for me think I'm demanding, probably annoying, and sometimes an ass, however I'd like to believe they would also say they have grown because they were pushed, and I don't think they would say I'm unkind, or a jerk, or hurtful. I don't believe that's what is going on with TK.
