How can they do that with HTTPS though? HTTP sure they can happily MITM and redirect, but with HTTPS you need a valid cert.

  DNS.

    Connecting with https prevents any DNS poisoning, unless the ISP managed to get a fraudulently issued certificate or a MITM root CA installed on the end users' devices. Neither seem likely.

      It's not poisoning, it's blocking.

  Your browser shows a TLS warning saying that the certificate doesn't match. If you override it, it brings you to that page. This is not a DNS block, the IPs are owned by Google, Italian ISPs are forced to forward the traffic of a blocked IP to AGCOM's servers.
