Blender is very impressive proof that with a few years of hard work you can go from one of the worst examples of bizarre "open source ui/ux" into something very usable. Never would have thought it possible a decade ago.
A few years of hard work made possible by substantial injections of cash by a lot of the big players in the industry. Epic, Nvidia, Amd, Amazon, Intel, Meta etc. I'm sure the $150k/mo of continuous donation support also helps.
In this aspect, Blender is a very unique OSS project.
