And CAD is ridiculously complex. Students also practice like half a year to cope with the proprietary market leaders. I sometimes think people complain because they confuse tools made for professionals with some game on easy mode.
But yeah, FreeCAD also isn't on par with professional tools. It's surprisingly capable and has a lot of features. And they made it crash way less. 2 years ago it used to crash several times each project when adding some chamfers or some other easy stuff and I had to do lots of stuff in order or it wouldn't work. As of now I'd say it's perfectly usable for the average hobby project. Just don't expect any CAD software to be usable without any kind of background knowledge. There's other tools for that kind of 3D design.
