I haven't really paid close attention. Are we basing our assumption that Uber was a "bro-themed caricature of a corporate culture" off the sexual harassment claim that kicked off the uproar a few months back?

While sexual harassment is, of course, indefensible, that story didn't really make Uber sound like the frat house implied by "bro-themed caricatures", it just makes them sound dryly indifferent to the employee's complaint. Are there other events that gave Uber that title?
