To be less cynical, I think it would require editing to original submission. I also see why editing the “bad press” company submissions could have undesirable optics. So, maybe the mods just choose to be a bit more laissez faire than normal and lets the community self moderate the related posts. Probably within some reason in the comment section, but they allow us all to be quite critical in ways that could easily be considered against the HN guidelines and they’re not squashing it either. I think that is perhaps the best stance for them to take honestly.
