If you’re fighting a one man war for privicy? Yeah, that’s pretty much a lost cause. (Also, the “all or nothing” approach will leave you with a bitter taste in your mouth. Pick your fights, and accept that you’ll never be able to keep all away from companies selling em, and that sometimes, sacrifices to your privacy have to be made. Complete removal shouldn’t be the goal when it’s just you going at it–it should be the reduction of what they get as much as feasibly possible without inconveniancing the user)
If you spread and bring that war to the collective? That’s where things are gonna change. Slowly, yeah, but they’ll change.
