Google makes 3€ profit per user per month on big video ads, the most profitable type of advertisements.
There is no way Facebook makes any more than 2€ per user per month, so asking 10€ is blatant disrespect.
And if that 10€ would mean they stopped tracking it would have some merit. But no, it just stops adverts, your data still gets used for everyone elses ads.
Glad so many EU privacy councils saw through the lies and are suing Facebook.
