Absolutely this, you cannot expect Blender level UI/UX without blender level funding. The fundamental problem is that new users/inexperienced users/nontechnical users arent used to contributing bug reports or even proper constructive criticism.
Furthermore what people forget is that being a 1:1 carbon copy of a corporate software isnt inherently a good thing. For example Linux, I love Linux and I love the way it works. I use it not because its OSS but because I genuenly prefer it above Windows, I dont want Linux to be like Windows. I love tiling, I love Sway, I love Hyprland, and despite being in alpha I love the Cosmic Desktop. I dont care that tiling isnt immediately intuitive to Windows users, I absolutely love it.
While im at it I absolutely despise the idea that the Terminal is inherently not user friendly (especially with a shell like fish). The idea that just because somebody isnt used to something makes it bad. Or that having to use a wiki/look at the docs means its "not ready". All software is new to somebody at some point, that doesn't make it bad.
OSS Devs/Maintainers: Are you willing to contribute code or at least donate any money?
Users: Uhh its OSS, you should just do all the work for free with no funding. Also I demand that your software be as polished and complete as (premium proprietary software) I demand you do X, I demand you do Y, because im entitled to free software.
Keep in mind Linux had this opportunity during netbooks, Microsoft simply forced them to abandon Linux and threatened contracts. Yes, many computers shipped Linux and in what I can only describe as a blatantly illegal move (and cornering of the market) Microsoft forced them to use Windows. If OEMs like Dell or HP start selling as many Linux PCs as Windows PCs Microsoft can just threaten contracts.
Most people dont use Windows because its compatible with more software, they use it because thats what their computer came with. If computers just starting shipping Linux then software will come.
Marketing and market availability are the biggest problems. People need to be able to go into any store, buy a handheld/laptop/desktop and have it include Linux without them asking.
Many people use LineageOS and GraphineOS for security, privacy, and features that base Android simply doesn't ship.
