If you are reading Opensource.com, you might be able to code, and you are probably reading this on an open source browser on some elusive Linux distro. You probably have not seen a browser ad in years because you are running an open source ad blocker. You feel warm and fuzzy when you think about penguins.
Sadly, as superficial as it may sound, open source software also needs to be visually appealing for people who’re used to commercial software. Most (F)OSS software isn’t exactly attractive when it comes to visual design, and that makes people turn away. It’s only recently that open source devs are giving visual design the importance it needs.
“attractiveness” is very different from UX and it’s often quite secondary. Practicality and usefulness is more important.
