I know many people who like working at Amazon but I know there are many that don't.
As for the scamazon marketplace, that's a clear and present danger. Amazon's real strength relative to the Best Buys of the world is that is the "everything store" with a huge selection. The dark side of it is that the marketplace is much less trustworthy than most others (I'm sure there is some dark web site that sells drugs for Monero that is worse.)
I have corresponded w/ AMZN about product listings that are completely nonsensical, like they were written by GPT-0, and been told that they didn't want to hear any complaints about a listing unless I'd bought the item and been ripped off.
Now I like shopping, I like reading about products. I don't like sifting through word salad to find product listings. And the fact that AMZN just doesn't care (they say so!) is one more reason why it is the last place I shop for things instead of the first.
Contrast that to Ebay or Craiglist where the listings make sense (even if some people struggle to spell words like "cat" and "pig") and the sellers are overwhelmingly honest whether they are from the town next door or the far reaches of the "global village".
