>the state can deputize any company to snitch on the digital ephemera that constitutes our daily lives

this is not true, but in the way that makes your point much, much worse.

In the US, case precedent is already set that digital data that you don't physically own is not yours. IANAL, but my understanding is that the standards for digital search-and-seizure are lower for cloud services, not equivalent or (god-forbid) higher.
