> I know we instinctively want to frame this as a privacy problem

It absolutely is a privacy problem. If that information was in your house, the 4th amendment would apply and they'd have to show up with a real judicial warrant, so you'd know what was happening.

Even if that's the "system working as intended" (intended by who exactly? I'm sure Peter Thiel loves it), anyone who cares at all about their own privacy should be using providers outside of US jurisdiction, because the US government does not, in practice, protect its citizens against unreasonable search and seizure as described in the Constitution.
