I have never hosted a bridge before so I may get things wrong. Please correct me where I do.
I assume this channel may be public, so any privacy concern needs to take that into account.
In terms of implementation, I was thinking that there would be 1 channel hosted on discord and 1 room on matrix being bridged together.
The benefit is that users of matrix and users of discord can participate in the same conversation without having to create an account on the other service. That way, matrix users don’t have to create a discord account or download discord app, which would be a good outcome in terms of privacy.
Edit: I have a faint memory that this is possible if the owners of the channel set it up on both ends. But I can’t find what the bridge is called, maybe it’s a different service from discord? Or I may have misunderstood things,
