Not from what I can tell. From what I can read, it only establishes a new authority, under the supervision and at the digression, of the Member state that can, with judicial approval mandate "the least intrusive in terms of the impact on the users’ rights to private and family life" detection activities on platforms where "there is evidence [... ] it is likely, [...] that the service is used, to an appreciable extent for the dissemination of known child sexual abuse material".
That all sounds extremely boring and political, but the essence is that it mandates a local authority to scan messages on platforms that are likely to contain child pornography. That's not a blanket scan of all messages everywhere.
> platforms that are likely to contain child pornography
So every platform, everywhere? Facebook and Twitter/X still have problems keeping up with this, Matrix constantly has to block rooms from the public directory, Mastodon mods have plenty of horror stories. Any platform with UGC will face this issue, but it’s not a good reason to compromise E2EE or mandate intrusive scanning of private messages.
I would not be so opposed to mandated scans of public posts on large platforms, as image floods are still a somewhat common form of harassment (though not as common as it once was).
