Back in the day it was just OpenOffice and LibreOffice. When did OnlyOffice come out? And, more importantly, did they call it that after OnlyFans became famous for some reason?
Edit: have done some googling and I thibk personally I'll be sticking with Libreoffice. I can see the utility for Windows folks making a switch but I often find open source tools which do not try to copy the proprietary alternative. Some of the best FOSS like Krita were successful because they broke the mold of slavishly copying UX and tools from bigger companies. Ditto with Godot to an extent.
Btw it was indeed called OnlyOffice after OF had taken off. Their name change was in 2022. Maybe I can sub to clippy and get him to uncurl! FOSS projects are so bad with naming and logos.
