Why will anyone trust something based/developed in the USA related to security? It's a compromised jurisdiction. For anyone creating security products who wants to be credible will need to be based somewhere that respects privacy.
Every single US citizen is complicit? Man, I would hate to be this jaded. Some of us are fighting against mass surveillance as hard as we possibly can.
This is as silly as saying that all of the people who live in North Korea are brutal dictators.
That's not what xmr claimed; what was said is that the US is a compromised jurisdiction, and of course everyone developing something in the US is subject to that jurisdiction.
It was never implied in xmr's post that every US citizen supports mass surveillance, only that they may be legally forced to participate in it.
