Basically their entire shopping ecosystem didn't make money for years and years and years.

""" Bezos chose to start his company in Seattle because of the city’s reputation as a technology hub and because the state of Washington had a relatively small population (compared to California, New York, and Texas), which meant that Amazon would have to collect state sales tax from only a minor percentage of customers…. [T]he University of Washington produced a steady stream of computer science graduates. Seattle was also close to one of the two big book distributors: Ingram had a warehouse a six-hour drive away, in Roseburg, Oregon """
In other words, Bezos was well aware of the sales tax advantage from the start.
Better prices wasn't the only reason for Amazon's sucess. A wider catalog was also a big deal, and paying sales taxes wouldn't have impacted the size of the catalog. Afaik, they also did well in states where they had nexus and paid sales taxes from early on, too.
They provided a lot of value initially but now any remotely commercial query has only sponsored links above the fold. If you want to sell anything on the internet, you're probably paying them or facebook a hefty vig. They also used their position in search to push their other products, they make you pay to buy keywords for your own trademarks, they aggressively track you in order to build an advertising profile, etc, etc.
Enshittification is well documented in tech. There is some initial value or innovation and then it always turns into gatekeeping and value extraction.
I thought they break "misusing user trust". Google is the ultimate surveillance capitalism engine.
They also regularly get in trouble for anti trust.
