Facebook tracks you even if you don't have a Facebook account though. And if I signed up in 2009 did I really agree to sharing location data on a smart phone in 2019??
Completely aside I'm finding how much data my Android phone shares extremely intrusive.
You may have an argument if you never signed up, but if you did, you agreed (when checking the “I agree to the TOS” box) that Facebook can make changes to their TOS and you agree to the new changes. Basically, Facebook can change their terms at any time and there’s jack squat you can do about it if you want to keep using the site.
