How can Signal protect metadata? If the CIA hacks Signal's servers and sees a large encrypted payload coming in from me and going out to you, they know i texted you an image even if they can't see what it is.

As I said, I don't want to discuss Signal. Their website explains a lot of their protocols, but they do protect metadata. I think at least one of your assumptions is wrong.

  Signal does not protect metadata cryptographically; it protects it via benevolence of the Signal server operators. Things could change any minute. Rollercoaster protects metadata cryptographically by optimizing an existing cryptographic technique called mixnets for the group setting.

  Discussing Signal is somewhat unavoidable in this context though.

In which case I feel the need to share this very interesting talk from Moxie about the negatives of decentralization from the POV of product. I have no education or horse in this race, but I found this talk very interesting and dare I say brave. https://www.youtube.com/watch?v=Nj3YFprqAr8 https://www.youtube.com/watch?v=Nj3YFprqAr8 Would love to be pointed to the best counterarguments, but again the focus on product was the interesting take for me.
