For one, they can still be held to account through individual lawsuits. Also at least part of the reason behind class action lawsuits is to streamline the lawsuit process. If a lawsuit ends up taking 100 years because that's long it takes to adjudicate each class member (which was the case in a prior unrelated lawsuit), then arguably a class action lawsuit is a poor fit. As the saying goes, justice delayed is justice denied. If you're allergic to nuance and want to round these considerations off to "you can't be held to account if you wronged too many people", then go for it, I can't stop you.

I'm allergic to the idea that these "individualized issues" cannot be resolved by some well-written queries on the sales database. Of course it is in Amazon's best interest that the court not think like a programmer.

No-one's suing Amazon for this on an individual basis. And nor is any lawyer taking this case for a few bucks (literally).

That doesn't mean there has been a wrong. That's part of the purpose of a class action.
