It's certainly not the right platform. It'd be one thing if they had any official communication on the matter anywhere else. Maybe they're ashamed and are trying to limit the visibility while only technically issuing an announcement.

They announced this exclusively on X.com, which ranks barely above Pinterest in terms of usage. That's below Reddit, Snapchat, WeChat, and Instagram, and requires a user account to view profiles and posts. And that's ignoring all the reasons X is a divisive platform with an extreme political bent.

GitHub chose not to announce this on any other social media either (BlueSky, Facebook, TikTok, YouTube, LinkedIn, or Mastodon, as of this posting, and with no emails sent on the matter.)
