I'm skeptical of all cryptocurrency, but in regards to this:
What is wrong with centralization when a core principle of Signal is privacy? Federation often complicates and confounds efforts to make things more private - look no further than Matrix's Olm implementation. MegOlm also encrypts far less metadata, by design and probably out of necessity.
centralization invites central control and observation...
imagine if talking to the people around you required you calling a central phone depot first before being connected to the person next to you... its not necessarily less secure, but there are more opportunities and the risk surface is greater.
Meanwhile, our Lemmy conversation is just like that, except instead of one central telephone provider, there are at least two (yours and mine). The risk surface has doubled!
