I'd say Amazon's "flagship product" is its platform, not so much its delivery. You might call it a platform+delivery-logistics vertical. Regardless, their ownership of the dominant platform for ecommerce does put third-party vendors (and possibly consumers) at a disadvantage.

This is a good point. The major negative impact of Amazon is on labor rights. I had a sobering conversation with a canvasser who came to my door last week; they were gathering signatures for a local bill, but their other job was at the Amazon warehouse, and they suggested that walking in the hot sun and talking to hostile folks in their home was far easier than running up and down the halls of Fulfillment.

It's a common sentiment that Sherman Antitrust was a prerequisite for prosecuting and breaking up trusts a century ago; we needed powerful legislative tools in order to even define and understand the abuses that those corporations brought upon us. Similarly, I have heard many people suggest that we will need new legislation in order to properly describe what Amazon has built in terms of systems which deliberately abuse labor, control shoppers, and grift the public.
