I'm biased on this though, as someone this might impact (https://news.ycombinator.com/from?site=thume.ca). From talking to other technical bloggers the consensus does seem to be that when we put a lot of effort into a technical article it nearly always makes it to the top of https://lobste.rs/ and /r/programming because it starts on the front page there but will sometimes flop off new on HN and maybe only make it months later if someone else resubmits the post.
I'd rather have eclectic ideas and projects from HN users not be overlooked (thus encouraging more of such content), and am less worried about GAFAM announcements, CNBC/Axios/BBC news, or things already popular on Twitter/Reddit.
Would this be a doable change to try?
Also, a lot of those media and BigCo stories really are of interest to the community. We try to dampen the stuff that's repetitive, and most of those sites are downweighted by default, but HN would not get better if they were excluded. It's all just more complicated than it seems like it might be.
What ultimately matters is how interesting a story is, not what site it comes from. I'm suspicious of encoding proxies for that, because it would be easy to end up optimizing for the wrong things. https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor...
