Which of the following is NOT a benefit of using public frameworks and standards?

Widely distributed knowledge is a genuine benefit because it reduces training costs and makes hiring easier when staff are already familiar with a common framework.

Many widely adopted public frameworks, such as ITIL, require organizations to purchase official publications, training, and certification materials, meaning they are not always free. The absolute claim of 'always free' is factually false and therefore cannot be listed as a genuine benefit of using public frameworks.

Validation across diverse environments is a real benefit because it means the framework has been tested in many contexts, increasing confidence in its applicability and robustness.

Providing a common language is a legitimate benefit that facilitates communication and collaboration between organizations and their vendors or partners.
