Different things.

AGCOM (Autorità per le Garanzie nelle COMunicazioni - authority for integrity in communications) is what supports the anti-piracy efforts that are fighting Cloudflare (as well as ensuring competition in telecom markets etc etc).

GPDP (Garante per la Protezione dei Dati Personali - guarantor for the protection of personal data) is the data privacy regulator, tasked with ensuring that people's right to privacy is respected in a world of databases.

Don't think so, this the "Garante della Privacy", two different institutions.

Different — but driven by the same mindset, the same nonsense, and a system run by recycled old-guard politicians.

No these are two different Italian agencies.
