That's a very narrow (and in my opinion even wrong) understanding of what constitutes a democracy. Prosecuting companies via criminal lawsuits might be the American way but that does not mean every democracy has to have those same rules. If an administration fines a company and there is the possibility to appeal to a court that is also a democratic process. My homecountry Germany uses this process (companies are never sued in a criminal lawsuit) and I don't see a reason why that would be undemocratic.

>The EU is not structured like that

Neither is the US. Numerous state and federal agencies have the right to directly levy civil penalties. You have the right to challenge those penalties in court, as you do in the EU.

First: this is a civil law fine. In the E.U., companies are not subject to criminal law, only individuals are. It’s not much different in the US, where antitrust actions are also civil.

Second: Google can appeal in court. It’s exactly the same as it is in the US.
