Quite common in tech billionaires. You think Mr. "I hunt my own food" Zuckerberg will run under the Libertarian Party banner, now that he wants to play in politics? LOL... I give it worse odds than a snowball's chance in hell.
The other commonality is that most of them stole their ideas... blatantly ripped off someone else's idea once they realized how big it was going to be.*
The only one that started, and stayed, libertarian (and completely frakking crazy) is McAfee. And his video about how to uninstall the anti-virus software his name is on, but he hasn't been associated with for many many years, is absolutely hilarious. Well, Woz too... I love his pad of $2 bills he has made up (real $2 bills, bound like a notepad) that he uses to pay stupid people for things with, so they freak out and think it's fake money. **
* I'm still watching for something to rip off. LOL. Americans love the tech guys who rip other people off, and idolize them. I might as well have a nice turboprop if people are going to be that stupid. Hey, as long as they got their iPhone, they'll cheer you to the ends of the Earth for stealing whatever it took to start your tech company.
** McAfee and Woz actually have talent and can build things, interestingly. They both needed lying marketing wonks to make their stuff sell, though. Anyone want to be my lying marketing wonk? Salary == $0... no benefits... but you can have some toilet paper known as "founders shares" ... go sell that crap, baby! LOL! MAKE ME SOME CULTISTS! (Well, once we figure out what to steal...)
