This is a bit overblown. Amazon doesn't have the retail sales of Walmart even in the US. Walmart has been able to dictate to manufactures rules for packaging and distribution for a couple decades now. Somehow we survived and now they are being disrupted. Europe may be "vulnerable" to US tech companies but it is not clear they will be as successful in China, India and other parts of the world.
All you have to do is see how India has been handling Apple, keeping them at bay and out of their country.
