Can you explain the difference? I find that coinjoins are already a big step up from mixing.
Some people wish bitcoin did something with homomorphic signatures but I think these people just have a shallow understanding of cryptography or imagine it to have advantages over coinjoins that they, in fact, do not have and just want to use cool tech for the sake of cool tech.
I think it's mostly just a rebranding of coinjoin to sound less launder-ous.

I have the same feeling. Anyway, on LN we have a even much better "collaborative spending"... LN is a "infrastructure collaborative spending" machine :)
