Actually that is exactly what it is:

”Thank you for your continued patience as we have thoroughly investigated your account access issue. Please be assured that we conducted a comprehensive investigation, exploring every possible avenue to restore your access.

Our product engineering team has confirmed that your account was suspended from using our Antigravity service. This suspension affects your access to the Gemini CLI and any other service that uses the Cloud Code Private API.

Our investigation specifically confirmed that the use of your credentials within the third-party tool “open claw” for testing purposes constitutes a violation of the Google Terms of Service [1]. This is due to the use of Antigravity servers to power a non-Antigravity product.

I must be transparent and inform you that, in accordance with Google’s policy, this situation falls under a zero tolerance policy, and we are unable to reverse the suspension. I am truly sorry to share this difficult news with you.”
