We don't have any interest in censoring this—it's being moderated the same way we moderate anything else in this category, regardless of which way the political vectors point.
You guys are cherry-picking a tiny and arbitrary sample of datapoints—i.e. what you happen to notice, when you happen to be looking, which is (1) a tiny time sample, and (2) strongly influenced by how you feel about the story. Other people who look at different times and/or feel differently notice different things and come to completely different conclusions. Then you (some of you, at least!) turn those unreliable, sample-biased and feeling-influenced observations into flaming arrows and fire them at the mods—the same mods, btw, who turned off the flags on the story in the first place.
This is interesting... I believe you that no one at HN is putting their thumbs on the scale here. But I suspect what's happening is community censorship by "hivemind" like a post on reddit critical of Democrats getting downvoted to 0 in r/politics by the community because many of them are. Or actual nazis getting praise on 4chan...
Why is tech overwhelmingly Democrat-donating/leaning? Even more interesting, perhaps.. There are 4-5 companies with a significant Republican presence, but at first glance I can't figure out what they have in common. Oracle? Old company. Intel? Old company. HP? Old company. Uber. WTF? And not Salesforce?! Not even eBay. Neither tech nor company age explain the majority.
There's a sociological phenomenon here I lack the skills/data to figure out, but it is very interesting.
