I haven't been counting, but HN has had lots of covid-related submissions and I'm pretty sure most have been from a majority perspective.
It's dangerous to make generalizations like "every $foo that makes it to the front page of HN". Such perceptions are notoriously subject to bias, for example the bias where people are more likely to notice (and put more weight on) posts that they dislike/disagree with than posts they like/agree with. If you think about it, that phenomenon would predict that all sides feel like the site is biased against their perspective, which is exactly what we observe.
