Just finished reading through, this is an excellent contribution to our understanding of the fedi's potentials and potential limitations in regards to online activism. Though this may fall outside of your definition of lossy, one idea that occurs, in comparison to the twitter experience, is that it and the other capitalist networks also introduce effective lossiness in the form of the algorithm (and more deliberatively, censorship). There were algo-induced Rashomon moments on twitter.

Would agree with your conclusion that activists could be better off in the context of non-centralized network ownership, assuming that further development takes their needs into account. Given sufficient critical mass, a hashtag campaign can achieve its ends under lossy conditions, as they certainly did on twitter; and here, with the fragmentation of moderative ideology and the prospect of a social media purposefully built for community organizing, possibly even more effectively. Lots to think about, great paper!
