Let’s say this is the official narrative. My argument:

1. Meta stands to consolidate power and revenue from further mapping devices to real people.
2. Meta was also originally backed by Peter Thiel, who trades in data mining for secret services, now much more energetically. Zuckerberg is a sexist idiot and his app had no more merit than MySpace. Thiel saw the potential of mapping real idenities to online behavior, and it is no accident Palantir was later implicated in Cambridge Analytica.
3. A redditor came up with concrete data that others have already posted, that show that Meta’s dark money are all over this case. As for the fine you say that completely explains this, is a very modest for Meta, who is used to pay such fines as a cost of doing business.
4. Amongst the orgs taking Meta’s money to push this are many conservative organizations, like Heritage but also others (anti-sex, anti-abortion, and anti-trans organizations), who know that these laws will effectively suppress speech. Much like the trans moral panics, the laws are not as stupid as they appear, but carefully designed to obliquely achieve their goals (e.g. police bodies with wombs, in line with the same orgs’ anti-abortion positions).
5. Governments watch closely as the new corporatist technofascism undoes regulations and checks and balances. They stand to gain from the turmoil and increase their surveillance capabilities even more. Alternatively, some EU goverments might be thinking that this is a way to stick it to US tech monopolies that brainwash their constituents, but they are wrong.
6. In fact, the approach and outcomes hints toward government contractors in cahoots with surveillance agencies, that it would be surprising if there is no adjacency to Analytica personnel and/or the benefits for state actors and spooks are just an unplanned side-effect.

Conclusion: There is sufficient basis to consider that the official narrative is not the whole story.

They’ve already decided so. It is all in Project 2025: queerness and sex-ed are considered pornographic. And platforms have been preemptively demonetizing and censoring info for similar topics (abortion and sex-workers resources also) for years.
