They can require ID verification of all users, as is done in some states in the US to access pornography sites.

Yeah, I have much more time in FreeCAD than PhotoShop. I don’t think it’s either intuitive or efficient, lol. But, I was surprised that I was able to both create model to both 3D printing, and create paths for my plywood router. In my experience KiCAD is near peer, because Altium also sucks.

Yeah, for all I know, GIMP is as intuitive and efficient as Photoshop. I.e. they’re both as un-intuitive to me, and I’m not efficient in either (I probably haven’t use PS in a decade). But, I guess being intuitive is a good “hook” in regards to market share. I am a software engineer, and do prefer (neo)vim, but I guess I started out on NetBeans. I kind of see that as a level-up in regards to efficiency; not sure if that exists in other industries.

Not saying GIMP’s UI is great (I only use it occasionally), but efficient UI isn’t necessarily an “intuitive” UI. I.E. an intuitive UI may not be efficient for a professional that takes the time to learn it and works with the UI ~40 hours/week.
