Okay so I had to look in to it because the site is not really doing a good job explaining it at all. Turns out[0] that they are voting for the extension of the temporary regulation thats been in effect since 2021 (Regulation (EU) 2021/1232). So this is about the "voluntary scanning of private communications" (which is still bad, but has been in effect for almost 5 years already).

Yeah so this is about CC 1.0 (which already exists)
While it's still worth fighting, it is less worrying
The question of course is, why something is allowed multiple votes (and the basic answer is - if it presented some changed - but I don't know if it's the case)
Here is the regulation that will be voted on: https://oeil.europarl.europa.eu/oeil/en/procedure-file?refer...
Note that the amendment was already amended on 11th March to set expiry to Aug 2027 and to also exclude E2E communications.
