Welp, I have just cancelled my Microsoft Office 365 recurring subscription.
Two reasons.
1. I only ever use it to check tracked changes to the copy edits on novels—once a year—which my publishers process in Word. As of this month, LibreOffice is good enough for the job (just tested at book length).
2. CoPilot in Office would open me up to accusations of breach of contract—my book contracts warrant that they're all my own work: CoPilot brings that into question.
So good riddance to Office365!
A third reason for ditching Office365 is that I have had a hate on for Microsoft's monopolistic business practices since the early 1990s AND a fourth is that Office is enshittifying rapidly—autosave only works to OneDrive shares now, not local storage, for example—and why am I paying for shit I don't want to use anyway?
Now the alternative is confirmed good enough, I'm out.
@ApostateEnglishman @cstross input fields are probably the only annoying thing about writer but otherwise I agree, it's great. What still is lagging behind a lot IMO is Impress, which is nowhere near the usability of PowerPoint. That said, Quarto or LaTeX/Beamer are way superior to both
