They're all pretty shitty, but Cuban is at least one of the less shitty ones. His work on reduced cost pharmaceuticals has been life-changing for some people, and is a really nice break from big pharma constantly trying to fuck you as hard as they can.
Yeah he's probably dying in the revolution, but towards the end. Assholes like Musk or Shkreli are far, far worse.
Compared to the other Uber wealthy, he at least seems to have some sort of a code of ethics from what i can see, which is obviously limited. He's still in it to make money (obviously), but his actions seem to suggest that he won't go to the extreme of hurting everyone else just for money.
I started liking Mark more when he opened cost plus drugs. It's a pretty decent endeavor to try to reduce pharmaceutical costs for the consumer
