Google has restricted or temporarily locked some user accounts related to the AI programming platform Antigravity, citing the discovery of a significant increase in activities considered "malicious use", especially when accessing Gemini models through the OpenClaw open source tool.
This move surprised many users when they suddenly lost access to services such as Gmail, Google Workspace or the advanced AI version Gemini 2.5 Pro.
The incident started when some users posted on Google's developer forum that they could not access their accounts even though they were still paying for the Gemini AI Ultra package.
Varun Mohan - former Windsurf CEO and engineer at DeepMind - said that the main reason is that the system detects large amounts of unusual activity originating from the Antigravity platform. He said that this situation has seriously affected the overall service quality.
According to Google, some developers have used third-party tools such as OpenClaw to connect to Gemini models, which is considered to violate usage terms.
The company said that it is necessary to quickly block the access of accounts that use services for improper purposes to ensure legitimate user resources.
However, the company also admitted that some users did not know this was a policy violation and pledged to support them in restoring access in some cases.
Not only Google, AI Anthropic recently updated its service terms to explicitly prohibit the use of Claude's account OAuth in third-party tools, including OpenClaw.
Similar moves from many companies show the trend of tightening control over the AI ecosystem, in the context of increasingly fierce competition between technology platforms.
OpenClaw is a type of "AI agent" capable of automatically performing multiple tasks on behalf of users such as email management, insurance transactions, or flight check-in.
This tool quickly attracted great attention after its launch at the end of 2025, with more than 100,000 star markings on GitHub and millions of visits in just a short time.
However, the strong automation capability also worries management agencies and technology businesses.
Some warnings suggest that if the configuration is not correct, open source AI agents can cause security risks, leak personal data or create opportunities for cyber attacks.
Peter Steinberger - framework developer of Antigravity - criticized Google's move as being too harsh and said that he may stop supporting the project.
Meanwhile, OpenAI CEO Sam Altman announced that Steinberger will join the company to develop a new generation of virtual assistants, while OpenClaw will continue to exist as a supported open source project.
This event shows that the AI race is not only taking place in technology but also in ecosystem control, as major companies are increasingly tightening access to protect their resources and business benefits.
