@mattcen And imho I think especially as a help/support platform for users and not just as an exclusive discussion room for devs (that might be more affine with stuff like IRC or XMPP) the ease of use of the platform is far more important than it being FOSS.

The average user doesn't care about FOSS (it's the sad truth).
They care about how easy to use and understand the platform is.

And in that matter Discord unfortunately wins by a long shot.
The alternatives have way too high entry barriers.
