Why does left or right even matter? This is ordinary stuff that should be covered? If you've read the article, you can see how - they were told to stop, and refused - lied about what they did to make the problem look smaller - reversed corrective action as soon as they thought the inspectors left This has nothing to do with bias. A right wing outlet should've covered this too. They might have used some different word…
The systematic bias arises from story selection, not from whether a specific investigation is accurate. So I am absolutely not suggesting this story is not accurate or that Boring Company isn't at fault. In the long run selective coverage creates an inaccurate picture of reality: constant stories about private greed, almost none about institutional self-dealing within the state.
Regardless, we are on a news aggregator here. Whatever selection bias this source has should be counteracted by hn drawing from many sources. At least on the source level. HN is going to of course be biased towards stories hn finds interesting.
