Won’t predators just use something else such as readily available open source software, reducing this legislation to a mass surveillance bill to spy on and control regular citizens?

How isn’t this anything more than a license to invade your privacy on this weak-ass premise that maybe you’re a criminal and stupid enough to use Facebook Messenger (or similar)?

This won't stop actual predators.

This will punish normal people, the actual criminals will just use something else, like always.

Fuuuuuccckk these inept computer illiterate idiots that come up with this..... Is what I would say if I didn't know this is just thinly veiled attempt #364163549 at getting rid of encryption so that they can monitor the everything while nobody else can, of course...

Ah yes, the pretence of democracy continues

I tried doing my part.

Criminals have already been using alternative ways to exchange data for a lo.g time, especially those who are exchanging images and videos (such as CSAM) as everyday messengers are completely inapt for transmitting such large volumes of data. And these algorithms will yield a lot of false positives too.

And it is the wrong signal to authoritarian countries as it makes people and companies extremely vulnerable. As Markus Hartmann, Chief Public Prosecutor in the German state of North Rhine-Westphalia, said not long ago on chat control:

"From the point of view of information security there is to assume an increased risk [of hacking]. There is no special expertise [demonstrated by politicians] in this area with regard to the signal effect for authoritarian states."
