@thomasfuchs I think you misunderstood the meaning of "open" in this instance.
This discussion is about consent, online safe spaces and online privacy in that order and none of these things has any connection to if the protocol used is open or not.
It is such a white tech bro (not you, the developer of the bridge) attitude to not care about consent by forcing an opt out model (which is illegal in the EU. I foresee him being forced to adjust things soon...).
