When there are hundreds of millions of Americans who are subscribed to the feeds of hundreds of millions of Europeans, and the Americans' feeds are generated via server-side queries, that seems roughly equivalent to a bulk transfer? It's querying a cache, at least, which is going to look rather like a database. I suppose they could serve all the Americans' queries out of Europe, but that's going to affect costs and latency, and the data still ends up in the US. I don't know what's going on at Meta, but possibly, they have a lot of technical debt and doesn't want to do a big rewrite of many of their systems for dubious benefits? And there would also be the issue of having lots of Americans' data in European jurisdiction. So it seems like what we're seeing here is supposedly "borderless" computer systems running up against legal realities. I suppose if it resulted in a breakup, it wouldn't be the end of the world, but it would be expensive.
