Additionally, if they leave the edit functionality intact for older posts they would have no legal grounds to stand on. It's not "hacking", or in any way unlawful, for a user to use an option provided by a company. I predict that if they want to do something about this they'll go the HN route and just make posts uneditable/undeleteable after some time.
