Just because you're paranoid, does not mean "they" are not out to get you...
An old saw, but worth another cut.
And as far as the Orwellian eye on us all, well, I don't see anyone able to stop it.
My old company bless it's heartless soul, use to bandy about its gleeful motto, "You can't manage what you can't measure."
Now isn't that a good reason not to expect privacy in the work place ?
There's quite a body of law domestically and internationally growing under that category called "The expectation of Privacy."
We are going there good or bad, unfortunately.
