I disagree with both points.
"Counterfeit goods" are 'black and white'. Not 'maybe good or bad'. They're either counterfeit or they are not. Maybe tricky to track down in some cases, but ultimately - objective.
Yes, stopping it might probably be fairly manual process involving process and overhead, but it's achievable.
Bezos spends $1B a year on his rockets - you don't think he can tamp down counterfeit goods for that amount?
I'm always shocked at people defending Bezos flagrant hustling of counterfeit goods. He can stop most of it, he knows about it, therefore he implicitly choses not to.

'Nazis = bad'? That's easy.
But this is not the subject at hand. You're missing the issue that the headline is misrepresenting the subject! Facebook has banned ads for Nazis, because that's easy.
We're talking about ads for 'Skinhead Bands' - or other ill defined groups. Well, Skinhead is a complicated subgenre, it's not black and white. But ok, ban that in ads. What about 'Reggae Skinheads'? 'Black Metal' - wait, is that a Nazi thing in Europe, or just basically 'metal'?
And what about terms in France? Ukraine? Algeria? Every culture has a broad set of terminology, sub groups and political dynamics that make this thing fairly difficult to interpret.
More important is the underlying fact that it's subjective.
Nobody can really satisfy all voices because we all have different notions of what 'wrong/evil/bad/offensive' is.
Just like there is effectively no way to ban 'hate speech' on FB because there's no globally accepted definition of what that is, kind of the same applies to ads.
They can stop Nazis, but maybe not some weird 'bad' skinhead subgenres that popup now and again.
