I think they do understand what they are doing. Just like with modifying a "protected" program locally, a native one. They are making laws about what you can and can't do, and outlawing tools allowing you to do that.

Honestly until it's possible to make laws forbidding you to do something that doesn't violate anyone, such will be made. If you can spend N money if forcing something through markets, and a bit less than N if lobbying for a law, then you'll do the latter.

Anyway. The problem is in the Internet and the Web as things which encourage this behavior.
