I am in no position to ask your question because I dont have the technical knowledge about how Lemmy works within, but I can share my perception of what happens in all internet medias: You are only going to see how truthful the platform is when the owners get a court demand or law enforcement at their doors.
Until this point you can hear a lot of sweet speech of defending freedom, protecting privacy or piracy advocacy, but when the police is involved is where things get problematic.
I am reading The Motorcyle Diaries by Che Guevara in spanish.
