"Progressive" isn't just a single spectrum, there are at least two axes: social and economic. Amazon is definitely socially progressive, but it doesn't look like that carries across to their economic politics.
Promoting postwar politics in 2022 is not progressive, it's regressive.
In practice, they're the same axis. There is no society without economy, and there is no economy without society. Plenty of people try to pretend otherwise, but the result is oodles of cognitive dissonance and mental gymnastics.
If you mean they are equal-opportunity exploiters, then ok I guess. But Amazon is not progressive at all, they are driven only by calculations of profit and power. It is no different to pseudo-progressive politicians like Obama, Hillary Clinton, etc. who for example had their public relations teams flip a switch on the messaging around gay marriage the moment that the demographic data showed that it was acceptably palatable to the general public.
