Again, you vastly underestimate the size of Meta.

In the last quarter of 2024 it shows a net income of $20,838 million. A $20 million fine would change that 3 into a 1 and again, that's net income for just for three months.

Actually GDPR fines can reach 3% of revenue if i recall my compulsory training correctly. That's a lot more than $20m for farcebook I would expect

I find it hard to believe any given post would have enough information to link it back to a specific person when viewed in isolation. Even "I'm Mary and going to visit my friend Sarah in New York City." isn't going to tell you who that belongs to if the profile and history itself is gone. It would have to be ridiculously detailed and all contained within a single post to actually reliably point to a specific person.

Containing personal information in general and even having an AI spit it out (which good luck, that's not really how LLM work unless there's something SUPER niche that essentially only you have spoken about) isn't enough to say it isn't anonymized. You also have to show it could specifically be linked to you by other people, in other words, that it can be de-anonymized.
