My experience:

1) I've been a seller on Amazon. 5 figure SKU counts, branded products. I was constantly being asked to provide invoices to prove that I had the right to procure and resell the products I was listing. I was also beholden to their metric standards and got delisted from the Buy Box regularly, until I could improve my numbers (operational bumps while we refined our processes... the standards were high enough if we fumbled a little bit, circumstances required a bit of time and attention to restore SOPs to required levels).

Not sure what these other entities are doing, but within the bounds of what I interacted with, and the age of my account, I wouldn't have been able to stay on the platform and keep selling if my fulfillment, returns and customer service metrics didn't stay within the acceptable thresholds.

2) I buy from Amazon regularly... household items, books, etc. So far, never had an issue with fakes. Always Prime, usually Fulfilled By Amazon.
