Counter point: KiCAD

Yes I know it's schematic capture and PCB layout, but I'm giving it as an example for two reasons:

1. The UX is genuinely really good and easy to use even for a novice following YouTube tutorials because it follows the norms of a schematic/PCB software package you'd expect to pay for (OrCAD, Altium, etc.)

2. It's open source and used in industry so GIMP and Inkscape have ZERO excuses for their horrific UX which is the prime reason industry professionals don't want to spend an age re-learning all of their workflows.

There I said it, I'll get down off this soapbox now.
