What does it entail, in practice?

They are sanctioned, okay, and? What happens practically.

US sanctions mean if you trade with the santioned org.. YOU get sanctioned (lose access to trade or financial systems controlled by US or US companies like Visa)

They will become pariahs financially speaking. Nobody will be authorized to wire money to/from them. It's brutal.

> Nobody

In the USA - the consequences should be only related to USA pertinent actors. The newspapers in Italy say, "there is no judgement against them in Italy".

The same mechanism that was used to sanction Russia, Iran - will be used to sanction A/I Collective.

If Italy doesn't shut down their services, the Italy itself will be shut out of SWIFT.

>...then* Italy itself will be shut out of SWIFT.

SWIFT is headquartered in Belgium. Only 2 banks out of the total 24 on the board of directors is US banks. Unless there's a hostile takeover of the SWIFT organisation by the US, I think this is a bit of a stretch. (Plot-twist: Italy is on the board of directors.)

SWIFT abides by international law and local laws. Including those against processing money transfer requests for terrorist organizations like A/I.

A US sanction is neither a local (to all of SWIFT) or international law. The question still stands.

Because of a decision from the USA administration? ?!

If you donate to them from the US, you probably get put on a no-fly list at a minimum. Maybe even a friendly visit from the feds at your home!

Anything between having their google profiles deleted to abducted and tortured at a CIA blacksite.

in this case, it mostly means trouble getting money, as they are funded via donations

The consequences may include the loss of:

  • Bank accounts and payment processing.
  • U.S.-linked donations and fundraising services.
  • Hosting, cloud infrastructure and upstream network services.
  • Domain registration and related technical services.
  • Certificate, security and email-delivery accounts.
  • Software and communications services.
  • Relationships with non-U.S. providers frightened by American secondary   sanctions.
  • Access for people in the United States who currently use A/I’s services.

My question now is whether European hosting providers sprouting up in the face of the US CLOUD act will step up to provide those services.

No, because they don't want to be banned from banks. With few exceptions, the US has power over all global financial systems. Also tier 1 ISPs (even the European ones), which trickles down to all ISPs.

Do you think many banks worldwide would enjoy declaring themselves the enemies of the US government in order to assist left-wing lunatics?

You misplaced "lunatics" in your sentence, though sadly the likely answer remains the same.
