Thanks for the heads up.
I just read both (Moxie and Matrix.org) and I will stay with Matrix response.
I understand Moxie points and the main one is about speed, as I understood. But, as Matthew Hodgson pointed out: the governance of decentralisation is hard, but not impossible.
So, in the end, Signal moves are driven by the market. And, IMO, sometimes it can be dangerous.
