I completely agree. That's why ultimately I abandoned the mainstream stuff (outside of YouTube. Yay monopoly) for discussion and go to Tildes for a lot of political talk. But Tildes is small by design and will have some blind spots.
I feel denying a quality article like this (or rather, upholding the minority's rule of denying) cracks into the idea that these policies work to keep HN high quality. Especially when what's on the front page right now is "I ported typescript to rust in a month with Claude!". These don't feel quality driven.
