I regularly comment on the Internet on my views on most schemes proposed to fix FOSS problems. They are mostly negative. I think that most of these schemes cannot achieve any meaningful impact. It seems that most of these disagreements come from the fact that I seem to work on different models of how FOSS work. Over the years, I have tried to share parts of my model. This is part of this endeavor.
Well it’s open-source now! Good for them. If you want more examples, you have a bunch of the self-hosted stuff (particularly Immich and Nextcloud, there’s plenty of great Jellyfin clients, loads of neat Navidrome/Subsonic clients, etc), LibreOffice/OnlyOffice (depending on whether you want separate office apps or integrated), you’ve got the Linux desktop environments (GNOME, KDE Plasma, Cinnamon, etc.), etc.
NextCloud is pretty meh. Worst cloud storage I have used so far. A hosted NextCloud with just a few users is also surprisingly expensive. Self hosting is only an option for people with too much time.
Linux actually has a couple usable DEs.
Nextcloud works really well for me. You don’t need to use all the functions, I just use it for file sync. Of course, you have stuff like Syncthing if you want something simpler (and peer-to-peer!)
