It’s not messed up, though. It’s just set to a different value.
If the exact amount of paragraph spacing is important to you, you can either set it before you print, share the file as PDF or use a proper layouting software. This isn’t a Linux issue, you should do the same when sharing a file with someone using MS Office.
Because opening a Word document in a different MS Office version than the one it was created with can also mess it up, but somehow businesses deal with that.
Your yardstick for a usable desktop system is “every detail and default setting in all software needs to be exactly the same as on the Windows equivalent”.
So by definition only Windows can ever be a usable desktop system. No matter how good anything else may be.
