I think the "joke" is if the US government orders a company to hand over that data, the fact that the servers are physically in the EU won't stop anything
It's one thing if they require the copy of data, and another thing if the President wakes up in a bad mood and orders deleting all the data. Imagine if the whole computing infrastructure for power plants, public transportation, banks, payment systems, large companies gets deleted in a minute.
You should not host the critical data on other country's servers.
