At best, you can conclude that outdated product design doesn't always ruin a business (clearly). But you can't conclude the inverse (that investing in modern product design doesn't ever help a business).
Case in point: tell me, from the point of view of the user, how many steps it takes to deploy a NextJS/React ecosystem website with Vercel and with AWS, start to finish.
However, I don't think it's fair to say that this trade-off always wins out. Rather, they've carved out their own ecological niche and, for now, they're exploiting it well.
The AWS APIs are so expansive, a product like this could offer a complete replacement for the default web console and maybe even charge for it. Does anyone know if such a solution exists? Perhaps some more generic "shell-to-ui" application? If not, I'm interested in building one if anybody would like to contribute.
