There are surveillance cameras even when you walk outdoors or drive your car.
There are also satellites which take pictures from above all the time and
send it to the governments. Is the solution to hide?
Modifying one's behavior because of all that will not change anything, it
will even make things worse. Even Snowden said that. That is the whole idea
of the panopticon - to feel controlled all the time and fear that.

Remember also that extreme avoidance of what the crowd does creates a much
stronger fingerprint of yourself. Not that I am suggesting that you give in
but be aware of all that. Running away has never sold any human problems, it
has always made them worse. We need something much bigger and much more
radical than simply not using this or that website.
