Don't forget the community's reaction to comments like yours, why down vote him if he's stating the obvious? FOSS projects often focus so much on technical features because everyone wants to flex their code-fu, but nobody gives enough time to UI/UX. Just look at pretty much every Lemmy web frontend, fugly webpages with early 2000s look-and-feel, usually slow and/or buggy, and with little to no user feedback.
This is not promoting FOSS. This is mocking closed-source/paid Lemmy clients.
I've been a Linux nerd all of my life and admire most FOSS projects, but seriously... FOSS nerds need to learn about the power of a good interface and UX. I'm a full-stack developer and there's no amount of elbow grease and backend wizardry that can beat a shitty skeleton with slick UI.
