A user checking out one of these URLs does not want to filter only local post on that instance.
On all instances, this url should mean “show me all /c/piracy on all federated instances”
If you really mean /c/piracy only on that instance, then add something to the url.
The current convention breaks the most important aspect of federation and makes its vestigial appendage.
The current way has user asking question /c/piracy, but on which instance ?
So now they’ll all join the same instance . You wouldn’t post anywhere else since no one would every see it.
It’s a recipe for centralization.
I think this is obvious to most users, were deal with “voat with extra steps” here
…all communities named “piracy” are not the same, the full community name technically includes the instance, they are each their own “subreddit.” You could subscribe to all of them if you wish, or to just “the largest one,” but you can think of them as say “lemmyworldpiracy” and “beehawpiracy” and so on, they are just different communities.
It’d be like if two separate 15yo kids ran a fan page for their favorite anime character and expecting them to be identical simply because they are both about Goku, they’re just different “sites” by different people, they just aren’t the same thing simply because they’re about the same topic.
