The plethora of definitions for DRM and, to a lesser extent, TPMs can make it difficult to discuss these topics in a meaningful way. We suggest you read the following articles to better understand DRM and TPMs:
The above articles are not intended to provide you with definitions that everyone is guaranteed to know and use. Rather, they are a survey of the different definitions in use. Reading them will allow you to more easily identify how your definition differs from that of someone else. Because DRM and TPMs can have such varied meanings, we recommend settling on agreed-upon definitions before engaging in conversations with people, particularly policymakers.
WSIC is particularly concerned with Technical Control Measures (as defined in Types of TPMs, linked above) and their danger to content owners and users, especially when TCMs are protected by the law in inappropriate ways.
