To be clear, "having the right to do whatever they want" does not equal "they're not dickbags for doing it."
Musk randomly decided to rebrand and stole a username he liked from someone because he's an asshole playing at feudal lord. Sure, there's no legal repercussions because it is his website. Doesn't mean he's not a fucking douche for doing it.
But if I can't needlessly denigrate Mr Snowden, how am I gonna convince you that Men in Black was a documentary about the real aliens that are real and really landed on Earth and work (for real) with the US government?
With credible evidence? But I don't have any because my guy is so much better than Edward Snowed-in off in Russia!
