Off course, it is totally fine to participate in things and also criticise them, as that is how things improve. But if everyone obsess on a company not in the bottom of bad behaviour, this simply gives more power to companies behaving worse. One can off course claim that their criticism depends on the PR perception of the company,but I guess that's not fashionable.
I don't think the argument is everyone else does it. The argument is Amazon is paying much higher than many other companies for the same job, and still being focused over, while companies paying less get a free pass.
Edit: or maybe not.
Interesting concept when you consider how deep the supply chain is for all the raw materials. The provenance on lithium and silicon would be critical I'd think.
