Personally, I wouldn't trust anything that Richard Feldman was involved in. He was instrumental in making the Elm community a hostile and unwelcoming place[0]. To my recollection he has never come out and admitted that the Elm core team was wrong in how they handled any of those things, so why should anyone assume any better from Roc or anything else he's involved in?
It's commendable to reflect so publicly on this and to make it clear that you made a mistake. Not that it means much, but this comment and the one you linked actually softened my view on this debacle considerably.
