Earlier quoted context omitted.
Because, counterfactually, no Jeff Bezos means no Amazon means no abuse of Amazon employees. So, to some extent, Bezos and Amazon are responsible, even if they aren't wholly responsible.
As I mentioned in another comment: I think you get cause and effect wrong - and that is imho a big issue and makes the entire discussion really annoying. The destruction of the social safety net in the US allows companies to act differently in the US than in other countries. So: Amazon pays above minimum wage, gives more leave to its employees than legally required, has stricter safety standards than legally required…
In the USA, labor rights were earned by literally committing armed rebellion against corporate "company towns" [0], as in the West Virginia coal wars [1]. Without this, the USA would not have weekends or eight-hour workdays.
Even if Amazon did not exist, Facebook would still need a lot of computers and Google would still have a lot of spare compute, so public clouds might still happen. And if they didn't, well, maybe that's not a bad thing! It's not clear that public clouds are good.
The Washington Post is older than Bezos; it turns 143 this year [2]. Without Bezos, perhaps the paper would be dead right now, but perhaps it would be thriving, since the paywall on their online content was only built after Bezos took over.
I find your view "not even wrong" [4]; your history of the issue is so shallow that I can't even critique it without first establishing the historical context.
