"Your margin is my opportunity" as a famous business leader is fond of saying.
For another counter-example, take any business with low barriers to entry. Sure, one set of competitors go out of business, but you have new ones. Retail outlets tend to be a good example. Top retail brands change regularly as new ones come in and push old ones out. This has been going for as far back as I have looked. Therefore any retail brand should operate as if it will happen in the future as well.
As a thought exercise, imagine WeWork drove every office rental company out of business in the United States by running at a loss. To make a profit, they would have to raise their rents. When they do, any company can re-enter the market by buying or building office space to compete with them.
In some markets that is justified. Those where significant infrastructure is needed to compete. For example Amazon's network of warehouses and datacentres would be hard for a competitor to replicate at scale.
For other markets, that's not justified. For example Uber, a small scale competitor can operate with some taxi's and an app. They won't have all of Uber's capabilities for sure, but they can compete in a locality.
Amazon's bottom line might not have been that great, but most of the difference from the top-line regularly consisted of dumping money into expenditures in areas that were pushing huge revenue growth.
It seems like people are suggesting analysts are dumb and didn't really dig beyond a basic top-line vs bottom-line glance when discussing Amazon's business model.
Why do you say this? I find it unlikely that building out 2-day delivery was a major short-term driver of revenue. It was developing their moat. Similarly, building out a fulfillment service that directly cannibalized existing business was not a short-term revenue generator.

(If you want to be pedantic, they were unprofitable for "year", not "years" after IPO)
Ebiester’s initial comment on becoming profitable after IPOing with losses allows for either as a follow-up. We seem to have taken opposite readings without ill intent on either side.
In their 20 years they've managed to burn 10s of billions of dollars and they're still burning cash. Best case scenario they are still a decade away from generating more cash than they've consumed.
Sustained profitability is a different hurdle.
