Earlier quoted context omitted.
I've never understood what would happen if Google or Facebook just ignored EU regulations, claimed that they were not under the EU's jurisdiction, and ignored any judgement. Would the EU erect a great firewall at that point?
Couldn't they just take the money owed the usual way, by freezing accounts, confiscating assets, etc.? None of these corporations can feasibly avoid that without exiting EU markets altogether.
Ultimately if the fines or compliance costs get too high that's exactly what happens. A company that does no business in the EU is not subject to EU rules. But because it is such a large and wealthy market the threshold is very high. If Kazakstan passed a similar law it'd be a very different story.
