What is some crypto tech/company that you are disappointed how it turned out?

For me it is unstoppable domains. Like I know a lot of people will point to hardware wallets or whatever. And while that is a shock even today. I'm more disappointed in unstoppable domains because web 3 really have some valid points to it over what we have now. And I think it could've and still can make the internet better.

The problem is, unstoppable domains (where you can buy a web 3 domain), they went from pushing for web 3 to pushing it as an investment. They are pushing for making a quick dollar vs functional gain
