Trade secrets and copyright are both types of intellectual property. They aren't unrelated.

Well, they're both lumped into this bucket called "intellectual property". Indy cars and unicycles are both vehicles, too. They share the property of having wheels. That doesn't make them particularly related.

The laws for copyright and for trade secrets are quite different. In fact, when someone talks about "intellectual property" rather than about one of the specific kinds (patents, trademarks, copyrights, and trade secrets), they often wind up reaching wrong conclusions. They try to apply concepts from one kind of IP on another kind, and it doesn't work.

So: Theft of trade secrets isn't going to fix draconian copyright law, not only because two wrongs don't make a right, but also because copyright and trade secrets don't have all that much to do with each other.
