CIA is not stupid enough to break into a guarded data center in Switzerland or one of the less America friendly EU countries. They tell the NSA to look for security holes and spread narratives that only criminals use VPN hoping that a politician will notice and try to ban them, like what's happening in the UK.

Big tech services are less private than you think but almost every provider who cares about privacy is safer than you expect. Most of the people who work there are committed to their mission, and if they ever get a gag order someone will leak it in no time because they know exactly how to do it without exposing their identity.

Why would they serve a secret subpoena and gag order, when instead they can just drive to a secluded location 5km away from the super secure datacenter, dig a few meters down, passively tap a strand or two, facility and service operators none the wiser?
