I mean, even the victims themselves came out and explicitly emphasized that scanning chat messages does not help.
I'm feeling these politicians was not doing it for the victims. Instead, it's almost like the victims are providing reasons to allow the politicians to expand their own power.
The Accelerationism (see note below) part of me think it's a good thing, because a heavily regulated country is often also a backward country. Doing things like this long enough, then you get out competed by everyone else, your population shrinks to zero and your land gets reused.
(Note: The word "Accelerationism" in the Chinese dissidents circle means that, if a bad future is certain and it trends to destroy itself eventually, we might as well just let it happen faster, so the pain maybe shorter. More: https://en.wikipedia.org/wiki/Accelerator-in-Chief)
Look, EU obviously have a few good regulations. But a regulation must be correctly designed and implemented, and it must not punish good people. Scanning private messages is a punishment to all.
If EU must scan something, I'd say scanning all messages/phone calls sent out by the politicians might do more good, consider how much trust people put on them (maybe they shouldn't).
