People were discussing Jobs being a nightmare to work for, which is honestly very well documented. The question is, is it justified? I say no not really. Being a good leader doesn't require being an asshole. You seem to be saying it IS justified.
The analogy of a drill instructor worked perfectly I thought, since that stereotype exists for a reason. Outside the movie, that phrase is commonly used as shorthand for an uptight mean hardass. One example of a real story supporting that: my grandfather fought in WW2 and had horror stories about his, including getting kicked in the mouth by them.
Now you're backpedaling and comparing Jobs to a personal trainer. Nah, Jobs was an asshole and simping for him is weird.
