Something in the explanation is missing here. It's still not clear to me from any of the provided context whether you got approval to release this. At least from my understanding of your role, if you had approval and used an official google repository, you would not get fired for merely publishing code that accesses a documented API through documented endpoints.
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).
...By the way, on a different subject, 4 days ago, had read your comments on a different post dealing with Alzheimer's. Just now, asked you a follow up question, and it's easy for them to get buried in your hackernews comments threads, so thought I'd just mention it. Thanks!
Maybe I'm misunderstanding, but it really sounds like you knew the policy in depth, and even contributed to the design of the policy, but when it came to your pet project you ignored it by skipping the release process? Am I missing something?
>This includes side projects that have not gone through IARC, even for DevRel engineers.
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.
