Man it took me 3 days of re-reading to only now realize that there is OPENoffice that is forked to libre office, and ONLYoffice, which has strong russian origins.

Til that only-office is even a thing. Far too easy to misread when I wasn't expecting only as a prefix to office. I'm sure I'm not the only one that got tripped up.

Also PSA: euro office isn't a standalone offline office suite - it's web based and doesn't run standalone. Needs next cloud and quite a bit of setup to allow for that M$365 'experience'.
