Hmm. So, as I read the article, they've dropped the mandatory universal scanning (which has the effect of no longer requiring on-device scanning)... but added age verification.
Voluntary scanning (voluntary for the provider, not for the serfs^H^H^H^H^Husers) is already happening under some kind of temporary directive. So that's kind of codifying the status quo.
If they had just dropped the mandatory scanning, it might even be good to see it passed, in that it could eventually, slowly, drive all the users either to providers that don't scan... or better yet to P2P. There are probably some players who accepted the lack of mandatory scanning because they're betting they can find "noncoercive" ways to coerce all the major providers... but P2P is a lot harder to pressure that way. Even "mostly P2P" is harder to pressure, just because the infrastructure required is smaller. And it's not clear that all of the people doing the horsetrading understand that P2P is even possible.
They've been coming back with this Chat Control bullshit every year, in an obvious "keep demanding it until you get a yes" strategy. But once they've passed something, it'll be harder politically for them to change it to ban effectively encrypted P2P messaging. They could end up screwing themselves.
BUT the age verification ruins the whole thing, since it torpedoes privacy in general, and it probably, depending on how it's phrased and who it binds, effectively bans P2P messaging.
I wonder how many people involved intentionally took that into account, versus how many just saw AV as something vaguely authoritarian that could be put in to placate the forces of Control(TM).
