Ireland is probably taking a plausibly deniable angle where they put companies in a position where they're practically going to not implement E2EE.
All this nonsense about "client scanning" is to distract from this. This is like Article 17 all over again, where Axel Voss MEP pretended it wasn't about upload filters.
Another factor is that one of the main "experts" the Commission is consulting is a white knight Hollywood actor who created a start-up a couple of years ago and is running around making impossible promises.
He has next to no actual knowledge or experience in this area.
The main selling point of E2EE is that it's private and secure. "client scanning" is neither private or secure.
It'd also be very easy for people to see it failing, asking questions, and to start to think that a company is trying to deceive / manipulate them.
From a business perspective, it would not make sense to implement. It'd be crazy to implement. That is probably the point.
