I mean, EU has some de-facto BigTech giants like SAP which are on same anti-competitive side. It just happened that US was quicker and more successful in various areas including software.
EU tactics on protectionism is creating legislative framework to apply tariffs to competing imports(i.e. import taxes and quotas(TARIC, etc), ecology-related fees, subsidies for local industries, restricting imports of goods for private citizens by postal limits and others)
I am not sure what you are trying to say. My whole point is that regulations are required for a sane market.
The fact that the US wins because they don't play by the same rules does not mean that it is fair.
And the fact that the US bans Chinese tech when they do to the US what the US does to the rest of the world shows that the US doesn't find it fair either. It's just easier to accept an unfair situation when we benefit from it.
