I have lots of criticisms of the EU and the censorship is lamentable, but this sounds like whataboutism to me. The EU does more for certification than other governments, but even they can't do everything. Is the US going against any of these things? It is only reasonable that they go for the large players first and foremost. Yes, they should do even more, but even the EU has its limits. And I'm quite in favour of going after fast fashion.
It is whataboutism, and it's also wrong because GP seems to think the cases covered in big media are all that's being enforced. It's much more, as pointed out in a comment below: https://www.enforcementtracker.com/
