I think this is actually a reaction to the over-reaching laws various governments are enacting. This is the way it should work - parents check a box that says "the user is 13 years old", and then apps and websites can see what the parent set.
This is much much better than having to do face scans and credit checks etc. to prove to some sketchy third party that you are over 18.
I think if Google had bothered to do this 5 years ago we might not be in the shitty situation we are now, but it's probably too late now.
That's what gets me. It's not like one country demonstrated this then the others followed, it's in parallel. Reminds me of when big US corps kept virtue-signaling around political things at the same time, whether it's now or previous administration.
If it just takes a few hundred rich people meeting up a few times a year to manipulate the world economy of billions, that says a lot about the world to begin with.
