HW backdoors are probably not something that brokers like these leverage so its a different topic. They just like making easy money from ad tracking systems, they dont wanna work hard and fuck around with zero days.
If you have physical security worries (government trying to kill you) then you either need graphene on a pixel and hope there are no RCE HW backdoors or something else entirely or no phone.
But the “tracking by default” in normal phones, with data being easily available is an issue that affects almost everyone not just high risk individuals.
Yeah its entirely expected. Its a global trend and its not gonna stop.
