I think you're misinterpreting my arguments because it suits your preconceptions if that were the case. GCM is not just client code. I clarified when someone said the client could be replaced.
I have read this; I don't generally comment on issues I'm not informed on.
Moxie is simply wrong on many of these points, and has been for a while and has had this repeatedly pointed out with no change in opinion. I would rehash this here but you'd be better off simply reading the linked thread and looking at other rebuttals. In particular I remember a 500+ comment GitHub thread on the Play Services issue where Moxie was repeatedly dismissive and rude to those who take issue with the glaring security problems in Signal.
