'Unlikable' and 'Asshole' are different things.
A lot of people are just cold, unsociable, not charismatic, don't buy into the latest social trend - and are therefore 'unlikable' to many.
It's possible to be 'perfectly good' and yet perceive as 'unlikable'.
Personally, I like those people, but the mob turns on them quickly.
Being needlessly callous, or mean, lording over people, excess egoism i.e. 'asshole' - this is unnecessary.
Being 'demanding' is not being an 'asshole'.
Firing people on the spot for missing this or that, is 'asshole'.
Emotionally, a lot of it can feel like the same thing, so it's confusing. And often people are a mix of both things, and are otherwise professionals, but let slip some emotional stuff now and again. The more demanding or terse a person is, the easier it is to cross the line into just being a jerk.
And it's not even necessary to be 'unlikable' either, but for 1/2 the population who tend to be 'people pleasers' maybe they need to learn that it's not just a popularity game, and the system would benefit from honest input.
My instinct says that Jobs and Musk are 10% nice, 80% terse, and 10% asshole.
Most of their actions seem to be on point, the kind of 'hard truth' actions that some people seem to admire in business types, but they can also be needless dks.
Some people are just plain callous jerks and actually have no business ability at all, and yet millions of people seem to believe their acting! Trying to think of an example ...
