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
I think where we differ is whether Lemmy is pointless without truly distributed communities. I come down on the side of “it’s not pointless” since there’s a huge and growing install-base of mostly* compatible servers, clients and users that means the cost of switching communities is low, and the threat of switching may be enough to keep mods from implementing unpopular policies. More worrying to me is the admin of your home instance, where your identity is located, going rogue, getting hit by a bus, forgetting to pay their hosting bill, etc.
