I agree that it can be difficult for people to hear that a place they enjoy has issues with anti-Blackness. It can feel like a personal attack, and most people consider themselves ‘not-racist’.

I think the real thing to strive for is to be ‘anti-racist’, rather than ‘not-racist’. We all ultimately have prejudices - the point is are we able to simultaneously be honest with ourselves, forgive ourselves, and improve.

In many ways, the overall reaction to this piece actually proves many of its points. The overall reaction seems to have been to deny that the problem exists and refuse to investigate further (or, as you point out, to recognize that the Fediverse being discussed extends beyond Lemmy).

Additionally, some of the reactions here are themselves examples of anti-Blackness (e.g. accusations of so-called “reverse racism” and the like, as well as the ‘knee-jerk’ downvotes you describe). Which makes me less inclined to think of Lemmy as any kind of bastion of anti-racism!
