Usually I get why companies release their UI frameworks. I've strongly considered using Atlassian's and AWS's frameworks in the past to build web apps because if it's good enough for Jira/AWS, it's probably good enough for my B2B saas app.

But I personally don't know why anyone would reach for this framework. Maybe if you're building a Windows app and you want a very consistent look and for your app to feel "native", but aren't there better options out there for doing this already?
