Even if this was the case - if companies treating their customers' data like shit vanish from the European market, I'd be really happy. Not a big loss at all. :

Even if this was the case - if companies treating their customers' data like shit vanish from the European market, I'd be really happy. Not a big loss at all. :) Additionally, leaving the European market opens up a big opportunity for EU-companies. Basically, that's the way to go if you want to wreck American dominance over the Internet (and the companies which matter know that very well, which is exactly why they are NOT dropping the EU). For European citizens it's a win either way. That's why nobody is impressed by your threats - they just look like people pissed off because the EU is now doing what the USA had been doing for decades - meddling in other countries sovereignity. (If you want to interpret it that way, which imho is wrong.)
