Hence many people are wondering if you released this without approval (that's my guess), if you used a Google repo to do it (from what I can tell you did use a google repo, but not an officially supported one, and other teams at google use this repo to publish code), and whether there were other extenuating circumstances, or if it was "the workspace SVP called my division's VP and told him to fire me" (just a guess for another firing mechanism).
In short, the way the post is framed, and the reality behind it, don't seem to match up, and people with experience are asking for you to clarify. If you don't want to go into more detail, that's fine, but... many people (like me) read what you wrote and thought "there must be more detail than this, because it would be silly for somebody to get fired for doing their job in good faith, and following the rules"

So did you do this "Launcher2" or "Ariane" thing and get the approvals? If so, it seems your ass would be covered. If not...
I can sympathize that the process seems convoluted and could particularly bite a DevRel accustomed to more autonomy. One would hope Google would do the whole blame free retrospective thing and improve the systems.

Also plenty of official Google organizations that are not /google/ , but have official projects.

I wouldn't read too much into it, since it can mean virtually anything.
