They aren't likely to read through everyone's email, but they'll send them to the government, just like a bitch, at the drop of a hat.

Also, be warned, if you work there, then they are likely to read through (or scan through with automation) your personal emails with intense interest. Don't pretend they aren't that nosy, because they are.

Also, for those with AdWords accounts, the employees on that team (and maybe others) can look through all your data at any time. Maybe things have changed, but they can log into any AdWords account using their internal system, and what they will see will be exactly what you see when you log in, and more. And to cover it up, they usually point the hostility of blame for unethical behavior at someone, then react in an extreme fashion to make it seem as though they treat privacy seriously, then turn around and continue doing exactly what they were doing in the first place.

This same idea is true for almost every other company. They pretend as though your data is private and as though they aren't sticking their nose into or selling your information, but that couldn't be farther from the truth. They sell everything, and they are always looking for ways to tie everything about you together, especially if you are an employee there, so they can hold it over your head and pretend everything they then say is true, because "they have the data to back it up."

It doesn't take much effort or a great stretch of the imagination to realize this is happening once you see what these people look like, or once you see what these people are like. It's so easy to tell when someone is full of it, that just taking one look at these people will clue you into the fact that they are guilty on all charges.

And when I talk spying, I'm not talking tying information together while not linking it to someone's identity, or tying information together, but using automation to do it so that a human being can't jump in and snoop around in someone's business. I'm talking about them deliberately trying to stick their nose into specific people's lives (and then everyone's) by trying to get as much information about them as possible, then turning around and trying to throw it in their face. Nothing well-intentioned, though obviously even if they meant well what they are doing is still shady and wrong.

Don't underestimate how nosy these people are. Just think back to the nosy gossiping bitch from high school, or think about your nosy next door neighbor. That's what they are like. And they can't breathe properly until they know everything about everyone. But then they have to cover up their bullshit, as they do in every other arena of life, by being loudly and strongly opposed to all spying, snooping, or misuse of data, and by dealing aggressively with anyone misusing data, as long as it's not them. They especially like reacting aggressively to these situations when the person accused hasn't done a damn thing, as they get to screw over someone innocent (they really get off on doing that), while making themselves look good, and while, in their minds, making it impossible for you to realize that they are the guilty ones ("these idiots are dumb enough to think I'm on their side when I'm the one doing it to them, haha, they are so stupid"). The louder these people are about being against spying on users (just look at them), the more likely they are to be doing it.
