I actually think the main problem is that they aren't even willing to admit that there is a problem. It's the classic "our program is great; if users have issues it's because they are using it wrong / didn't read the manual / are stupid".

Go and look up why you can't run scripts with `python3 foo.py` on Windows. It's like a one-line fix and they've come up with all sorts of naysaying reasons rather than just adding python3.exe (which Microsoft did years ago in their Python packages).
