Some quick googling: Estimated users of Facebook: 3 billion. Meta annual revenue: $120 billion 3 billion × $200 is significantly more than Meta's annual revenue. There's paying for a service and there's being ripped off.
They aren't going to get anywhere near 3 billion subscribers.
In everyplace where they can offer users a choice between the $200 subscription with no targeted advertising plan and the current no monetary cost but they use your data for targeted advertising plan most people will choose the latter.
