Considering the fact that #Matrix's reference implementation pushes towards #AGPLv3 and is thus non-free and very restrictive to license, I wished for #XMPP+#OMEMO / XMPP+#PGP/MIME or #IRC or #Zulip integration instead.
But maybe that's me who found Matrix to be on-par with #Spack, #RocketChat, #Mattermost & #MicrosoftTeams when it comes to bad #UI & #UX.
I sincerely wish for said #Chat system to be either a dedicaded #App or modularized, but then again I wounder how much value it could add compared to #Gajim & #Pidgin...
Please fix the bugs and make Thunderbird better...
Consider buying up #Beonex or implementing proper #MAPI support instead...
