Reminds me of the story the other day, "Meta found 'covertly tracking' Android users through Instagram and Facebook" with the STUN requests being sent from web pixels back to localhost Meta apps (FB/IG).

I just don't think anyone can be using Facebook/IG, especially persistent mobile apps, while have any real concern about tracking.

Does FB still run their Tor onion service? That seemed to be the only possible way to use these products in the past without being subject to extreme tracking.
