I don't think big companies will back out of the EU at all. In fact, they now have a big more of a competitive advantage because they have the money and time needed to get GDPR right over a smaller company. And transparency about how they use data will isolate less users, now that they already built their name. I think it will affect smaller companies more whose new innovative product will be tested on the US market first before demand is recognized and then adapted to the EU. Of course it really depends on the regulatory reach of this law.
