Final answer:
It is false that an Azure service in public preview is released to all Azure customers, as the public preview is a testing phase before it becomes generally available and might not be fully supported or complete.
Step-by-step explanation:
The statement that an Azure service in public preview is released to all Azure customers is false. A public preview is a phase in the release process of a new service where a wider group of Azure customers are allowed to test the new features. However, it is not yet generally available (GA) to all customers. During the public preview, the service may not have all features implemented, and there may be more significant changes based on feedback before it becomes generally available. Azure customers participating in the public preview should be cautious of using these services for production workloads, as they are not fully supported and might be subject to changes that could disrupt services.
