Not who you are replying to, but I think mass surveillance is bad and evil, period. So, any person or company contributing toward mass surveillance is bad.

Most bad things have some good part you can point to. Mass surveillance and all of the other police and government aiding technologies usually point to improved conviction rates or something similar. But making police more efficient at convicting people isn't the only goal of society. That's only one part of what makes up a country and it's society. And, as the saying goes: "Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety."

That's beside the point? Gaining security by losing freedom was always on the table. What's interesting is the cultural shift toward not caring about losing freedom.
