Curious on your thoughts about Kroger/Great Value/Archer Farms (Target) brand items? At least Amazon marks them clearly as house-brand, Archer Farms is practically camouflaged at Target among the brand names, and it's placed pretty prominently too.
Personally I think it's hard to draw a distinction between the two cases - either they're both fine or they're both not. My line would be closer to: if Amazon noticed a certain thing was selling really well, created their own version of that thing, and then de-listed the original thing from their store, that seems like the point at which it becomes anti-competitive to me.
Store brands are an age-old practice so it's interesting to revisit them in the context of mega-corps like Amazon. Although WalMart+Great Value is probably a similar scale.
While they don't delist items, their algo favors products they sell directly to the extent that Amazon will get the buy box over a third party seller even when that seller is reputable and cheaper. Add that the 3rd party seller has to pay a sales fee to Amazon, often making it impossible to compete with them without approaching zero margin.
It's not delisting but it's the next best thing. If Amazon starts selling something you sell, your sales are gone, you were just free market research for them.
Which is still the same in the Target example where their own brand product get much favourable placement. This practice has been going on for so long possibly before all of us on HN were born.
It is a tactic often used in dispute, that is why Brands needs to work on Branding to combat this stronghold from Distribution. And one reason why small brands likes the Internet so much rather than working with conventional distribution channel.
A direct comparison would be target putting your product behind their product on the shelf where the shopper can't see it without digging for it.

cruelly -> actually
Walmart and Costco do it too, should that it be banned when customers get the product at a cheaper cost?
Bookstores are no longer viable, because Amazon has obviated the need for a brick and mortars store, and it passes the benefit on to both consumer and author alike, in reduced prices and thus increased sales.
Since Amazon is not in the authorship business itself, since it gets an equal profit on all books, its book business is a lovely example of markets working to further society.
Amazon's problem is in the use of data metrics on its giant store to create products that compete with its partners. The Amazon Essentials line is anticompetitive IMO, because as the operator of such a large platform, Amazon has a responsibility to the US economy.
