Something that’s getting lost in this conversation is the nature of the infringement and what that means to the copyright holder. Memes could be considered a form of infringement, however in practice they often serve as free publicity. The intent is not to deprive the copyright holder of revenue, but use the medium to express themselves. Exposure increases, and so does the likelihood of revenue from the conversion of new fans.
This changes with public conversations of piracy, because the nature of those conversations drift into how to deprive and evade the copyright holder by providing users just enough information to find pirated content. From a legal standpoint this can be used to prove aiding and abetting, a crime that be considered equal or an accessory to depending on the jurisdiction.
The admins are aware of how Lemmy’s content caching works, and now publicly acknowledge the existence of their federation with dbzer0; whose piracy communities are its strongest asset. Any defense of ignorance is out the door. Without banning the communities LW becomes an accessory if dbzer0 becomes liable, as would any other instance who caches dbzer0’s c/piracy.
To those who still disagree, that’s fine. Open your password manager, make some new accounts on other instances, enjoy the lemmyverse. But you have to agree that it is unreasonable to demand you hold the evidence of my crimes because it would inconvenience me otherwise.
