Software and other IP companies claim much from the DMCA that is not actually present in the document -- or that can only be arrived at through semantic game-playing -- often pointing to it as a carte blanche to violate contract law and bully consumers. They continue to succeed at this because most consumers lack the resources to challenge such behavior in the courts or the legislatures. End-user license agreements have met with mixed results in federal courts. Normally, if there is an option to return a product if it proves defective or the customer finds the conditions of the license unacceptable, then the license will be upheld in the event of a dispute. (The customer is assumed to have indicated consent by not returning the item within the prescribed time period.) Programs and files purchased and delivered over the internet cannot be returned, however, because there is no physical medium to return, and no way of guaranteeing the software has been deleted from the destination machine regardless, so EULAs in these cases cannot be valid. As to the status of crippling software features, I am not sure, which is why I said they are possibly fraudulent, not definitely so.
