I'm sorry but anti-trust for foreign companies is kind of a joke. The French government et al literally cannot "break up" Google or Facebook et al, all they can do is ban Google from their territory.
Also, deep and hearty guffaw from me regarding "the business moat is irrelevant". Thinking like that is why American companies dominate European tech and not vice versa, just saying. Thinking like that is why domestic competition just took a 40% hit in Europe as the business went to largely American firms. 40%!
