Yeah, but it's about who the thing is useful to, and how many people are in that category.
Amazon is very useful to the general population.
AWS is very useful to startup and corporations in general.
Zoom is very useful to the large amounts of people that like human interactions and consider text-only to be cold and distant.
Crypto so far is useful to... not that many people, and worst of all, many of those people are scammers and grifters and criminals. Many of the others it's "useful" to look a lot like marks, gullible people that lose a lot of money.
When a business the size of AWS decides it's not worth investing into it, that's a bad sign. They'll go for anything that can make them a ton of money long term.
