I think that most people would answer your question by saying "because I need Mac app XYZ and Linux doesn't have a nice equivalent yet". I used to have a MacbookPro. I'm now 100% Linux (Debian). In my particular case, the only reason I would go back to using a Mac is for Logic Pro X (music creation software). I've used Ardour and Bitwig on Linux, but Logic is still superior in many ways. Having said that, it's not enough to drag me back to Mac, and there's no way in hell I'll ever use Windows again on any of my own systems. Generally speaking, I'm now 100% FOSS, and plan to be so for the rest of my tech days.

Yes, LibreOffice in Ubuntu or Fedora are good enough technically, and there are same problems when exchanging documents with Office for Mac as there are with LibreOffice.
However, deflecting blame works. When exchanging files with someone and something is broken in LO, it is automatically fault of LO. When something is broken in Office for Mac, it is an uh-oh moment, as obviously it is the latest product from the same company, so the effort to resolve the issue is much more constructive.
Another reason is, that both Mail.app and Outlook are usable as Exchange clients (yes, I'm stuck with that, with IMAP disabled there :(). Evolution is a trainwreck. There is a plugin for Thunderbird, but it is a no-go, as it is a yearly subscription. One time price would be fine, but no way I'm going to pay yearly for using Exchange mail in Thunderbird.
