What facebook does is evil. 
But if you think other companies aren't constantly tracking you as well then I guess you're at best just misinformed? Or ignorant? 

If you have a cellphone, your location is being tracked and quite possibly your audio is being monitored. If you have a modern iphone, your location is being tracked, your audio is being monitored AND it is mapping your home layout with its depth sensors. 

It amazes me to see people complain about facebook (Rightfully so) and then whip out a fucking iphone that has never been without a connection in its existence and I bet they either use macOS or win10. It's absurd.
