The latter is a byproduct of how GitHub's upperhanding[1]/casting couch culture has overtaken the Web community and how a bunch of software gets built, generally. The Shirky era[2] is gone. You're not seen or to be treated as a neighbor showing up with a helpful tip that one of your pipes has burst. You're going to be seen as another person who wants something from them, or, at best, a starlet who can do something for the cigar champers and'll be willing to put up with a lot of crap because you're trying to build a résumé.
This in large part because of two design decisions that GitHub made early on: the contribution graph on profile pages and naming the bugtracker "GitHub Issues" (and promoting a culture where people with support requests are funneled into the same side door as collaborators trying to keep tabs on software defects—i.e. people who need a real bugtracker).
