As I understand it Cloudflare is being asked to block these sites globally, and what I said was that Italy doesn't have the legal authority to request that CF do so globally.
Locally, within Italy I can see the argument that CF can be compelled to adhere to blocking sites for any requests originating from, or being routed to Italy - so long as Cloudflare maintains any kind of presence there. That goes for any other country, too.
Realistically maintaining this kind of work puts a financial and engineering overhead on Cloudflare (or any CDN) for running operations in that country, and that incentivizes Cloudflare to push back on this request from any country. The logical response from CF is to refuse and threaten to remove all operations from the country if the country tries to force the issue, to prevent CF from getting pulled into the same requirements for multiple other countries, which is exactly what CF did a couple days ago.
I'll reiterate my previous stance - if a country wants to block part of the internet, that country needs to do it themselves and for the space within which they have authority to do so (their borders). At that point it's up to the citizens of the country to push back if they disagree, and if they don't want to be compared to China and their Great Firewall they shouldn't try and regulate the internet.
