I don't get your irony. Yes EU companies are smaller, do the fines are proportionally smaller, but they are held up to the same standard and fined as well. It's not some hidden scheme to extract money from the US.

Edit: it's definitely worse if you go deeper into the rabbit hole. Sister legislature, Digital Markets Act:
Booking.com insisted on the fact that it is one of the only European companies that is a global success and that as they are not the most dominant actor in this sector, they should not be disincentivized while competing with bigger companies.
So yeah, "please only punish non-EU companies" definitely sounds like a trade barrier.
