This might seem quite pedantic but I like the fact that they’re calling stuff like that out - over here office documents are more or less synonymous with MS Office, despite me having used LibreOffice for years with no significant issues (aside from their bibliography being broken while writing my thesis, super annoying but I found a workaround).

I’ve never actually had anyone complain about me sending them ODT or ODS files since even the said MS Office doesn’t have a big issue with those.

Oddly enough, if you ever also see a CSV, LibreOffice Calc will give you a nice import dialog whereas by default MS Excel will happily open it wrong and fuck everything up for you.

Edit: oh wait there was a case in university where I did a presentation in front of like 60 people and it referenced fonts that weren’t on the other machine and they didn’t get embedded in the presentation file. It fucked up all of the font layouts. Since, I do presentations in PDFs (the archival kind). Except recently I also wrote my own presentation tool that outputs HTML pages and can also serve everything from a folder, or I might just put them on my server. I think I reinvented worse Google Docs.
