Absolutely. Honestly, I took the presence of this HN post itself, and the fact that it directly contradicts my own first hand experience, as a really bad sign (for HN).
Very little has changed on Reddit since the protests. A few tight knit communities went to discord. But tons of people loooove to complain.
There may be biases from supermods, and that's an issue, but there's dozens of examples of diametrically opposed subreddits with thriving communities.
