Looking at the used market where I live, quite a large number of laptops are already sold with Windows 11 installed even when officially unsuported. Activated with MAS as well, probably.

Libreoffice is like the 2003 MS office but better, which makes it superior to anything in the market right now. Onlyoffice is number 2, as it has greater compatibility to MS office but it also imitates MS office, which makes it worse to me but easier to switch for someone addicted to Microsoft products.
