A more thorough explanation:

Definition: Circumvention refers to the act of bypassing, avoiding, removing, deactivating, or impairing a technological measure or device that controls access to a work protected by U.S. copyright law. This means that if there is a technology in place to protect a copyrighted work, it is illegal to try to get around it.

For example, if a music streaming service has a technology in place that only allows paying subscribers to access certain songs, it is illegal for someone to try to hack into the system to access those songs without paying.

In Scots law, circumvention also refers to the act of using a facility or method to get around a legal requirement or restriction.

For example, if there is a law that requires all cars to have a certain safety feature, it would be considered circumvention to use a method to disable or remove that safety feature.

These examples illustrate how circumvention involves finding ways to get around established rules or technologies, which can be illegal or unethical.
