In all seriousness, as an American I'd love to see a healthier, more well-distributed tech industry, but I don't see many companies stepping up to provide competing services. It's my understanding that china has alternatives to many of these products/services, but I really don't see how anyone in Europe could possibly use a US-free internet.
Maybe because the US dropped most of its anti trust regulations, leading to ridiculously monopolistic practices such as "acquire everything that may be threatening".
I can only think of Nokia, purchased by microsoft in 2014. Those phones ran windows CE before that even, so you could hardly have avoided the american tech industry.
All I'm trying to say is, it's impossible for Europeans to both A) be on the internet and B) avoid the US tech industry.
