Just make a law that states, in order to protect the citizenship from the dangers of CSAM, it’s illegal to use protocols like this or can’t operate in the country. Make a smear campaign to appease public opinion to say that cloudflare is helping hide CSAM sites.
Once this first step is done, the road to stricter filters for any other use is paved
All the filters that are used in Europe to block illegal soccer streams within 30 minutes or to block those dangerous gambling sites (just because they don’t pay taxes, not because of actual concern) are all coming from a “we need to find a way to block CSAM”, then “we already have the tech, we should apply them also to other stuff”
