One of the first guidelines, "Assume no malice", is one I take to heart, and wish it was applied by people here to this announcement.

Maybe you've never experienced any problems with the open source community. Personally, I know I never had. Even if most of us have positive experiences, there are some people who don't. These guidelines are trying to make it so less people have a bad experience in the future.

Having community guidelines doesn't kill a community. Hacker News itself has guidelines (https://news.ycombinator.com/newsguidelines.html), and I don't think we've suffered because of it. While the language of GitHub's guidelines is different, the goals seem very much the same.

Let's assume that GitHub is acting in good faith here, and trying to make things better for the community.
