FAANG - i think in this list only Google and Apple are run by MBAs.
Thus amongst FAANG its only N which is not 'run' by an MBA. Sarantos, who runs content, is a college dropout. Yes, Hastings does have a MSCS from Stanford- but he was also a liberal arts undergrad (Bowdoin) and a Peace Corps volunteer. Of all of them, he's got the most interesting story to me.
This isn't to say MBA's haven't screwed things up- of course they have. But so have engineers. Apparently the idea of engineers building cool tech with no use case has never occurred to anyone else here.
