Sale of "free" stuff on eBay

Have you ever tried asking a company like Google to pull your usenet posts from their archive, because they are violating copyrights? Did you get a response? To make a long story short: I did this a few years back and received no response. Like it or not, the only value in a copyright is if you are both willing and able to sue the individual who is violating it. If you are unable or unwilling to do so, then there is absolutely no point in having draconian copying policies. You may as well put your work into the public domain or place it under the GPL (or something similar). In either case you are likely to receive more contributions from third parties. If it is under the GPL, you may even have assistance if you have to go after somebody for copyright infringment (at the very least you can send the GPL lynch mob after them).
