Obviously debate is still on, as we see in here and in [0], and it looks like HN folks are not in favour of these integrations, including me. So question stands, how/why the debate was concluded, did all developers had a vote? Is there a link to discussion?
I have no idea why you think that random HN discussion afterwards (in response to an article filled with misinformation!) would have any bearing on how Firefox is developed.

There's been about 1.5 year of extended discussion and iteration over DoH, yes. I'm sorry but there certainly isn't just a "single" link!
