Price is a thing, but having the option to chose is definitely good.
Now comes the real question: do you really trust the Zuck to implement a “do not share/sell anything” policy ? 'Cause yeah, if I’m paying, I’m expecting that none of my data is being sold/processed/transmitted to another company. Paying to just remove ads is … pointless.
It’s possible, I’ve been tricked last year by a similar attack (the sneakiest attack possible to target privacy people, imho).
I praise IT Security for putting so many safeguards, sandboxes and verifications!
