@fristi @ejabberd Yeah that side of things is a lot harder, it's a bet that the libre software implementations would be at least cared for enough that they can compete with the proprietary ones when people can more easily switch from one to another.
An even bigger bet would be for people to use that two-way street to move from proprietary to libre.

You could worry about standard bodies governance or about them being forked but I think implementations naturally get priority over standards (as seen when there's broad consensus/refusal of implementations compared to the standard), so I'm usually not too worried about that part.
