I claim this is not about "protecting children", but to mandate age sniffing on the OS level eventually.

I also find this all questionable. A 18 years old is not penalised? So why is that a difference? I should say that I don't use "social" media (unless commenting on a forum is called "social" now), but I find the attempt to explain this ... very poor. I could not try to reason about this. I could not claim it is meant to "protect" anyone at all. Is this pushed by over-eager parents, who don't understand what to do on a technical level? I really hate censorship in general. So, even while I think unsocial media such as Facebook should be gone, I hate any such restrictions. Then again I also don't trust any legislator who pushes for this - I am certain this is to force age-sniffing onto everyone. And then extend this slowly. Step by step. Salami by Salami. Until anonymity is gone.
