pg: Several of those companies send people to Demo Day, and when I saw the list I thought: we should stop inviting them. So yes, we'll remove anyone from those companies from the Demo Day invite list.
I don't know the context of that decision but I'm fairly sure even if pg is being inconsistent that two wrongs would not make a right so I hate seeing that kind of rebuttal being handed out as if it's a QED. It is not. It's whataboutism.
