A lot of the claims about Piefed have been debunked. I once spoke with someone who was absolutely certain that communities with “shit” in the name couldn’t be federated. So I showed them a link to lemmyshitpost on Piefed. Somehow, they were still convinced of the claim, even though they’d seen the evidence for themself. They’d read the code, but they refused to accept that they’d misunderstood it.
