So a set of barely maintained applications that cannot support modern Hidpi screens that are shipped with almost every midrange laptop (except Thunderbird which is the only passable app in comparison to its alternative).
The rendering of the Office file formats by the LibreOffice is dogshit. Feature parity is a rounding error. LiberOffice UX is completely from last century. There is so many little UX things that MS added which are so out of the league (like live content update from Office 2007!) for LibreOffice and its outdated codebase.
The Office alone can maybe replaced partially in Linux-compatible environments. However the MS Office-integrated prosumer software ecosystem is the thing that keeps people on Windows. Unless Linux people redesign the whole ecosystem to be as accommodating to closed source app ecosystem and find a time machine to replace all the existing Windows ecosystem, nothing will change.
You are getting downvoted, which is sad but also a testament of how delusional the fanboys actually are. Not that I don't think doesn't have its uses cases/upsides.
The reality is that even without talking about the UI and various stability/compatibility/performance (oh god) issues there are even some very basic missing functionalities that ones will encounter regularly when doing stuff that is not just low-level administrative filler work.
If one company would decide to invest in developing a decent competitive alternative it could be worthwhile but, in the meantime, most people are better served with browser-based stuff.
Either the Google stuff, free Microsoft version or even the newer Proton offering are decent but there are some semi-commercial offerings that can be decent too.
On the surface LibreOffice is all right, but the hard reality is that it is way too much of a PITA to work with for most people to bother unless they really don't have a choice or are forced too for some reason.
The fanboys don't like that reality and would rather deny it instead of working on fixing the issue; which is precisely why it's a lost cause.
