It's an empirical claim. I'm not seeing the articles!
I spend a lot of time giving feedback to people about how to appeal to HN's audience. Authors tend to be founders only for very-early-stage startups, such as the ones you see in Launch HNs. The authors from larger companies tend not to be founders or even execs. My sample is biased, of course, but if founders and execs of successful startups were writing informative articles about how they run their startups, readers here would be interested and we'd surely see them posted.
