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.

It's often not allowed to sell nicotine or alcohol to those who aren't penalized either
