Or one guy running all that stuff was so horrendously oversubscribed that keeping them running at all was an achievement?
I've never met a single person who uses Gnome Web (Epiphany) instead of Chrome/Firefox/Brave/Vivaldi/whatever. Or Totem (instead of mplayer, mpv and its various frontends, or VLC). Or Boxes instead of virt-manager. Or gedit (instead of the trillion text editors that exist on Linux. The thing the platform lacks the least? Text editors.). Oh wait, it's not gedit anymore, they wrote a new one from scratch called "Text Editor".
I will say that I wish they had stuck with the Epiphany name. It was much easier to search for, either in web search engines or in order to launch it in Gnome with whatever their Spotlight clone is called.
