You can't attack Big Content in any meaningful way, because the unimaginable (again) amounts of money they spend bribing Congress and the White House makes you absolutely insignificant as a voice.
And there's your solution:
Stop giving them money! Period.
We bitch and moan about all the bribery (I guess some people still call it lobbying, or access) that goes on, while at the same time we give them all of the exact same money that they're doing the bribing with.
If you want things to change, stop giving them money. Choke off their air supply.
You might think that your choice to not buy CDs and movies won't make a bit of difference. And you might be right. But there is no other way to stop them except by cutting off their supply of money.
Make them irrelevant in your life. Don't buy their music or their movies. Read books (I know), from the library if possible. Read more from the Internet (I know) and blogs, there's an amazing amount of free, quality content swimming around out there.
Make your own content, and be content with less content.
