Surely all decent people would want to control on-line internet predators cyber-stalking and grooming children; that is a given, as it is evil. And all righteous people would support sensible legislation surgically drafted to do this, without having hidden political censorship produced as a side effect.
The EU Child Sexual Abuse Regulation, CSAR, while seeming to be good on a superficial level, has the problem that critics see as a great over-shooting occurring, with the ending of proper encryption and private messaging in the EU, and once this is done in the EU, there will be pressure applied to do this across the West. Online services would have to scan all messages and images to search for any offensive material. This would totally end privacy, and create a situation even worse than the original evil that was to be addressed. And, that is the point, not to deal with the online predators, but to censor any political content that the system opposes, the real motive here.
