the whole point behind it was them making an assumption about something
What makes you think the change suggesters assumed ill intent?
The submitted PRs seem to reason improvement, not accuse the original author. I see them suggesting a change, neutrally. With (minimal) objective reasoning.
/edit: I see the later ones did. But the first one didn’t. And the second one arguably didn’t.
The original text had ‘he’ where ‘it’ was correct. Which supports part of your premise.
They also merged a change request that changed those instances alongside ‘they’ instances. I don’t know if the original author and denier was involved, but it’s certainly important context missing from OP blog post.
