PTB, this seems really like they’re overstepping their bounds, @Demigodrick@lemmy.zip has clarified the matter.

Unfortunately this isn’t the first time Lemmy.world has done something like this using “legal” as an excuse, and probably won’t be the last time. They’re too big so they’ll never get defederated or penalized by any server wishing to stay even remotely relevant so nothing is likely to change.
