What happens to the accessibility of a knowledge base when user criteria is set to none?

When user criteria is set to none for a knowledge base in ServiceNow, it allows read/write access to all users. This means that anyone within the organization can create, edit, or delete knowledge articles, as there are no restrictions on who can access and interact with the content. This setting is often used when the intent is to encourage collaboration and input from a wide audience, fostering a more dynamic and comprehensive knowledge-sharing environment.

In contrast, if specific user criteria were applied, access might be limited to certain roles or groups within the organization. Thus, the absence of user criteria (indicated by setting it to none) directly equates to open access for all users, which encompasses both the ability to read and write articles in the knowledge base.
