I tried FreeCAD, I really did. I gave up due to constant crashes and terrible UX and went to Fusion. Even though it's slow on my laptop it's still a far better experience. I am never going to commercialise my models so it's acceptable for me.
(Note: I would have tried Solidworks given the reasonable hobby pricing, but it's Windows only, and I don't want a web-based CAD tool)
My hypothesis is that certain products need users and feedback to be good. Maps is one of those, hence why they had to release it in a ‘bad’ state. Apple AI I think is another such product.
I've wondered the same thing. I think one benefit is that it looks like HTML, which means it looks similar to what you see in the browser's DevTools, which makes it easier to compare and debug.
