alt Hacker NewsDid they stop tracking people through their like buttons by now? If not, there's no argument - they're literally tracking non-users on every site they can! Besides Google, what company is doing as much tracking as much as Facebook?
Wasn't it just last year that it became known how Facebook and Instagram apps track your browsing through WebRTC? That alone is far far more than people knowingly give them.
Learning about their tracking web browsing through WebRTC ports from the apps, you have a point on users not knowingly providing that. Still, if you dissociate from Facebook (not having their apps, not being logged on, etc.) then that tracking would've been ineffective. The rest of my comment stands on their being able to leave it.
