I think the worst part is that I don't trust the parasite that is Meta to not still track paying users anyways. If anything, they're probably more likely to be tracked even more invasively after they pay up. You telling me the company doing all the shadow profile crap is gonna suddenly stop tracking you just cause you pay up? If you believe that, I've got a bridge hot off the presses for you.
And what happens if you stop paying eventually? You've just indicated to them that you're a juicy target to harvest data from, so you're even more fucked and are gonna get even worse privacy intrusions than ever before.
