The users aren't random "human beings" in this case. They are professional software developers who are expected to understand the basics. Deploying that model into production shows a lack of basic competence. It is clearly marked "preview" and is for test only.
This case was simply a matter of people not understanding the terms of service. There is nothing more to be said. It's that simple. The "engineers" should know that before deploying to prod. Basic competence.
And I mean I genuinely do not understand what you are trying to say. Couldn't parse it.
"At Preview, products or features are ready for testing by customers. Preview offerings are often publicly announced, but are not necessarily feature-complete, and no SLAs or technical support commitments are provided for these. Unless stated otherwise by Google, Preview offerings are intended for use in test environments only. The average Preview stage lasts about six months."
