It's becoming obvious that Google is rapidly being boxed in by various countries. Several years ago, the EU courts created a Right to be Forgotten, in which people in EU countries could complain to Google and have certain results about them removed... in that country's localized results (i.e. French citizens would have their unflattering data scrubbed from google.fr, not google.com or any other country). This seemed to work for a while, but France demanded all results be removed worldwide. Google has since moved to geo-located filtering while litigation with France is pending.
This week the EU announced a $2.7B fine against Google for anti-trust violations. It's unclear what regulations Google may face in light of that. Today, the Canadian Supreme Court ordered worldwide removal of search results for a company.
It's obvious that the global regulation genie is out of the bottle here. I expect more countries to start issuing rulings like this, mandating changes in Google's rankings. I also expect these rulings will become more intrusive (some in France want Google's algorithm made public).
The question I have is this: if Google has nothing within these countries, or simply withdraws its physical presence, what political actions could be taken to compel Google to comply?
Note: While this touches on legal issues, the actions to compel would have to be political in nature since the enforcement would have to be between countries. i.e. if Google were to withdraw to just its US footprint, how would the EU enforce its ruling then, since their only obvious recourse would be to block Google's website, which would be unpopular.
