EU based
Companies which have their headquarters in the European Union fall under jurisdiction of the EU and the member state they are in. They are obliged to follow EU law, EU court orders and of course the law of the particular member state they are in. The EU has one of the strictest privacy regulations. Also many checks and balances are in place which make EU regulations and policies slow to change, but this ensures that extremes can be stopped very effectively.
