Your problem is that you're trying to promote a story that the community just doesn't agree with you about. This is clear from the comments at https://news.ycombinator.com/item?id=17245018 as well as the other threads you guys have posted about this. The comments are nearly unanimous, and now users are starting to react against your over-promotion of the story (e.g. https://news.ycombinator.com/item?id=17245116).

When people post things that HN users consider off topic or against the site guidelines (https://news.ycombinator.com/newsguidelines.html), users flag the posts. You can call this censorship if you like—one person's flagging is another's censorship, depending on how they feel about the topic—but HN has had this flagging system for many years and it's a core part of how the community functions.

The flags are not coming from some sort of Microsoft or Github brigade. How do I know that? First because stories like this, where some users are trying to drum up drama but most who look at the issue don't agree with them, always get flagged. And second because I checked the accounts of the flaggers and they are longstanding community members with no history of activity around this issue.

If the community felt you had a case that this was a MS/GH censorship scandal, the story would be all over the HN front page and there would be nothing that flaggers or moderators could do about it. Your problem is not that there's a gang of flaggers censoring you. You just don't have the community on your side.

(Also, no moderators touched any of these stories, except to unkill them so they could re-open for comments.)
