I'm under the impression that only EU slaps antitrust charges lately.
It seems political. The EU is taking on a lot of US companies with antitrust complaints but few EU companies.
The EU has filed plenty of antitrust complaints against EU companies, but the reality is, particularly in the tech field, US monopolists are dominating. The fact that there are more US companies breaking the law, does not mean the EU filing more cases against US companies is political.
