It's not just about what people think. It's also whether they think hosting stuff on US servers is even legal. I can imagine the Pirate Party suing some EU groups (governments, companies, whatever) because they are using US providers, and the US is not safe enough to conform with EU privacy law. And there's money on the line too, lots of EU companies will want the contracts that are going to US ones. And keeping jobs onshore is always popular with the masses.
