>> US domination of "tech" is near total.
Not quite when considering China having the tech freedom they wanted. Also switching internet services is far easier than switching physical supply chains. The only thing that might be hard to switch is the part of the interent backbone infra that is controlled by USA.
You are not living in Europe, right? Because while I agree that China is a problem, the USA is a much, much bigger problem for Europeans than China is right now. It's mostly the USA that wants to depict China as the main problem when in reality the USA behaves in a hugely aggressive colonial manner. Trump just makes this more obvious, but that has been the case way before Trump already.
