To me it feels that the age verfication (adult de-anonymisation) push, at least in Europe, is coming more from the increasingly-authoritarian left as a reaction to the rise of the online right and Musk's Twitter.

(Maybe some unspoken element of concern over social media bots, too - as they evolve from spamming copy+pasted comments to being near-indistinguisable from actual human accounts?)

If you look at the people pushing these bills it's the anti-trans and anti-porn activists. Not the left.

It would be interesting to see a similar lobbying breakdown for the EU and UK. I bet it's still Meta with other right wing actors. The left rarely has the money for this kind of lobbying scale
