This is at least partly because the people opposing it don't know how to make a mainstream political case.

The case for is "catch child abusers".

People opposing it are talking in abstractions like privacy and right to use encryption. Which are important but you need to identify concrete harms that ordinary people identify with. You can't oppose a harm people can visualise and feel emotional about with an abstraction.

Opponents need to say "if this passes your kids might be taken away because of a bot looking at your photos" . "Even if you send a picture of your own kid to your own mum, you will have to think about whether it could be mistaken for child abuse by some minimum wage worker at G4S from a completely different culture, who has to process 20 pictures a minute"

The opposition mostly sounds butthurt that politicians are making tech decisions. And I say that as someone who genuinely thinks chat control is a terrible idea.
