One Facebook author and like apple iMessages which used xmpp they lock the anchor certificate to a walled garden.

They're writing standards and deploying closed ecologies.

I'm not getting the sense from you that you're especially familiar with how this particular IETF effort came together.

True. Since i'm familiar with Richard Barnes I'll ask him in Prague.

Your comments in https://qht.co/item?id=16325803 seem relevant.

I'm not optimistic about MLS, the standard. I also don't think it's a secret plot against open protocols.

I don't think I am a secret plot believer. I just observe apple and others deploy group communication software and person to person as walled gardens even when they use xmpp and like protocols.
