As a non-white Irish citizen going to school here in the 90's, I hear you. I've been through that.

But, I don't understand why people think a fork of his work magically scrubs his essence from it.

And are they also doubling-down on ensuring his future ideas and commit hashes never find their way into Amiko?

What's the long-term play here because I don't see it other than forking for the sake of changing ownership which does nothing to achieve what the author wants to achieve. A genuine fork which meets his criteria of abolishing DHH would be to completely change the direction and future roadmap while avoiding any future cross-DHH-contamination entirely.
