hijacking the message

one of the phenomenons of the modern age is the readiness those in power will take a message or movement and co-opt it to their ends. i mean - how much money has hollywood made on rebel movies? look at how the environmental movement has been used to justify taxes (gas, carbon) and intrusion into your privacy (in frisco they're going through your garbage to make sure you're recycling and composting). so the question is - how will/can the freedom message/tea party movement be corrupted?
