> LibreOffice is eating Microsoft 365 lunch
No way.
I love LibreOffice. It's fantastic. I rolled it out to a prior employer where everyone needed a word processor but we certainly didn't need to pay Office prices when we didn't have requirements that only Office could satisfy. A high point was when we were having trouble collaborating on a DOCX file with a customer, then they sheepishly told us that they weren't using Office, but this other LibreOffice (OO.org at the time) thing. We laughed and told them we were, too. That day we started swapping ODT files instead and everything worked 100x better.
And all that said, I haven't seen LibreOffice in person in years. Mac shops uses Pages & friends for internal stuff, but really, almost everyone not using Office 365 or whatever they're calling it now is using Google Docs. Google is eating Microsoft's lunch in this space, and my gut estimate is that they split 95+% of the office software market between them.
I do wish that weren't the case, but my personal experience tells me it is. I wish it were more common, and also that there was a virtuous cycle where more Mac users made it get more attention, and more attention made it feel more like a "Mac-assed Mac app", and feeling more like a Mac-assed Mac app got it more users, etc. I just don't see that playing out.
