The bigger shame is that it took Peter Theil's name to get people's outraged about this. Discord handed over their users' identifications to a third party without regard for how it would be used or secured. I don't care if it was backed by Peter Theil or Mother Theresa - it's a huge problem either way.
And they'll do it again too. They'll find a new partner - one with less baggage - to do the exact same thing and few people will bat an eye.
