I personally think that FB, Uber, RBNB, Oracle, Google, Amazon, and literally every american SASS should be completely forbidden from Europe. Period no discussion at all. Given the state of current America, given the reactions even on this very post that do not see how Cambridge Analytics has damaged the entire world - yes, I think it would be safe to put a good 10 year ban on every US web tech. It would fasten up Europe and leave out the important decision to someone who can actually make a difference instead of being washed out by some reddit / twitter with fake russian bots. Let the economics just move away and make the decisions for people who are in a state of hypnosis instead of playing with mass control and then calling it "freedom".
Keep your american movies and social networks please. Btw why is TikTok banned in US?
