Or .... NSA paid them to keep their mouth shut and look the other way until it comes out on its own and then just claim "oops, sorry"
Bingo. It’s mind boggling how people can be so naive when it comes to these issues. Intel has had backdoors for a long time in their processors. This is no secret or conspiracy theory. Also, it is completely rational to assume that Intel would keep open “flaws” that three letter agencies have discovered but “bad actors” haven’t as long as possible to allow three letter agencies to work their magic and Intel can claim ignorance.
But then again, all this is just conspiracy theory tin foil hat crap, you know ... just like those crazy people who thought Apple was manipulating their devices performance. ...... oh wait.
