Your own article admits it's basically used nowhere. That's important, because OP specifically claims that the US government has"access to all non-American's personal data". Moreover it was widely condemned, contrary to OP's claim of "but when the UK/EU wants something similar, suddenly it's a massive outrage. Is it just "we're stronger than you", so it's ok when we do it?".

My point is: the UK demands are bad but I‘m sure the US agencies have similar demands and also backdoors, I‘m looking at you Cisco, just not openly.
The UK is playing with open cards, the US don‘t. I trust neither but the US are more devious.
