I think the problem is really that law enforcement have got used to outsourcing this kind of policing to private operated platforms (at least here in Germany). I was actually at the local police station because I notified them via an online mechanism about sth that looked very CSAM to me in a random forum tracking some gossip/Internet meme (actually I did not really look further than a title because that can be already illegal). Just dropping the link (which I thought would be just auto scanned and sent into some central pool), led to the fact that I had to go there in person, wait and had to listen to a speech about the fact that it can be easily illegal to be in certain places in the Internet and that I should be careful because I had a daughter in the age. It was almost that they are threatening me. They told me that all the CSAM stuff anyways comes through the provider and that they would do raids if needed. They cannot do much anyhow on the state level if they do not get the local ISP and IP delivered. It felt rather absurd and somewhat scary/dystopian that there are Internet companies that sent cops out to do raids based on some IP. According to the police officer it seemed very effective.
