Ok, now I see. I actually agree with that point. I'd like to mention though that one model I really liked was what the one that Google landed on with Google+: a central identity only known to one entity and then as many pseudonyms as you want that you can switch between but that can only be traced back by the provider, and where they promise not to do it except for good reasons. Of course these days we know that such promises need to be backed by laws to really be effective, but what a nice idea - as long as the identity provider can be trusted! Also, when I think of it Telegram has something very close to this if someone wants to test what it feels like. And just like Google+ it is not totally obvious: you first have to create a channel, then you can reply to other groups as that channel. Maybe you must activate something in your channel settings too.
