Blender was extremely hostile to UI change suggestions as well until only recently when they changed things drastically with the insanely successful Blender 2.8 project. From then on donations (including corporate sponsors) grew massively. Blender has made massive strides in the past few years, and much of it can be attributed to them changing their stance on UI/UX changes.
