At first I thought it didn't matter that they can see what I do, because if I store a movie of my underground lair with nukes and a few F-22s in Google Drive, they can't use the evidence against me in court unless they get a warrant. But let's be real: if you've got a movie of yourself shooting some guy in the face in Google Drive, they're going to find a way to get that warrant before you delete the movie. And they'll have a copy of it to show the judge. You don't even know they've seen your not-so-secret stuff. The fact that they do this in a clandestine manner effectively makes it unconstitutional since the warrant protection is easy for them to circumvent.
