My view of Amazon's decline comes from being a "partner" in their seller and publisher ecosystems for years.

The seller platforms in particular (Brand Registry, Vendor Central, Seller Central, Transparency, etc.) have crippling levels of technical debt. The situation has only gotten worse with Jassy's reckless directive for the entire organization to push into Generative AI (https://www.aboutamazon.com/news/company-news/amazon-ceo-and...). So much basic stuff is just breaking down, and seller support is overwhelmed or unable to intervene to fix the mess.

You can see a small sample here involving problems with product attributes (https://sellercentral.amazon.com/seller-forums/discussions?s...). Google "Amazon AWD delays" or "Amazon CSBA problems" or "Amazon remote fulfillment problems" to see examples of programs that are unable to provide even basic levels of the services promised to sellers.

Meanwhile, Amazon has been so greedy with fees since Jassy took over that sellers of all sizes and many small to midsized brands are being squeezed out of existence or driven off Amazon. Its PPC ad platform is completely predatory, loaded with dark patterns and hidden defaults that add billions to top-line revenue while strip-mining the accounts of sellers who often have no choice but to participate in the auctions.

It's clear that Amazon is running scared when it comes to dealing with new competition, including the Chinese shopping sites and the looming prospect of agentic AI and other new AI-powered shopping tools eating its lunch. For the first time ever last month, I saw an Amazon search results (via Rufus) that actually directed shoppers to third-party brand sites. This would have been heresy 5 years ago.
