While this is definitely true, for a long time FreeCAD hasn't exactly made it a high priority to properly work around that.

For example, the Topological Naming Problem (as I understand it) is made quite bad due to OpenCASCADE design - but as we've seen with 0.19 and later it is possible in a lot of cases to work around that. But that's a lot of really hard work with relatively little reward, so for years it languished on the backlog, and users had to deal with even trivial designs randomly blowing up in their face for no clear reason.

The result is a CAD program filled with footguns. Nobody wants to address structural issues, so you just pretend they don't exist, hide a half-baked tutorial on a Wiki on how to work around the worst of them, and blame the user for holding it wrong.

Commercial applications can solve this by shoveling copious amounts of cash at any skilled developer who is able to make any real-world improvement - even when it's not a perfect solution yet. FLOSS applications have to wait for a developer to come around who is masochistic enough to tackle it for free.
