Something Apple does considerably worse than Microsoft, intentionally and purposefully - entirely for control and profit, mostly to maintain their app store taxes.
(can't comment on iOS since I use Safari there, but then TFA is about Windows 11 i.e desktop-side)
I can go on, but macOS is not an OS that respects users or user choice.
Do you mean Pages/Keynote/Numbers?
Since these are not 1:1 (neither on feature nor in concepts) with MS Office/OpenOffice opening such a file is by definition a lossy import, so saving in the original format would be destructive, both with regards to the original contents being lossily converted to Apple app concepts and any Apple concept specific change made after opening being lossily converted to the original format.
This is not user hostile, this is saving the user from the impedance mismatch between software that organically grew from Multiplan and software that's been designed from the ground up.
Now, the Apple office suite being "shitty" is largely your personal (and the way you phrased it, judgemental) opinion, I personally prefer the Apple office suite any day to MS Office/OpenOffice/GDocs.
Its like if you cheated on your wife and told her she can't get mad because your neighbor cheated on his wife first. Somehow that is a rebuttal even though she was never married to the neighbor and may have even started dating you in the first place because you didn't cheat.
Apple open webviews in Safari, does not respect the user's choice at all, and doesn't even allow you to install a non-safari browser on their mobile OS.
This is like peak irony. Apple is the walking definition of this problem.
