As I see it, someone who "listened to that feedback, swallowed their ego/pride" would include a note at the end of the post about the edits. Admitting you were wrong requires not erasing the evidence of what you said.
(He did post a kind of vague apology in https://ziggit.dev/t/migrating-from-github-to-codeberg-zig-p..., but it's ambiguous enough that anyone who was offended is free to read it as either retracting the offending accusation, or not. This is plausibly the best available alternative for survival in the current social-media landscape, because it's at best useless to apologize to a mob that's performatively offended on behalf of people they don't personally know, and usually counterproductive because it marks you as a vulnerable victim, but the best available alternative might still tend to weaken the kind of integrity we're talking about rather than strengthen it.)
