How is this actually supposed to work in practice, other than sharding EU and non-EU customers and having them unable to communicate across the shards?

Meta’s chock full of very smart, highly paid people. I’m sure they’ll figure something out.

Why unable to communicate? Is there any reason why the relevant non-EU customer data cannot be stored within the EU as well?

[daveoc64]

If someone in the US visits a profile page of someone in the EU, that necessitates a transfer of data outside of the EU.

Perhaps that's an extreme and pedantic example though.

Confidential Cloud computing is the answer and hyperscalers work on that. You literally put your data in a black box.
