This is a very idiotic way to think. Gnutella is a free and open network. If people do not want to share, cannot share etc. that's perfectly fine. They might share in the future or share the files they have downloaded. If you think that someone's a free loader or selfish just because he doesn't share at any given moment, you have a very narrow mind. If people cannot download because of that, they'll consider Gnutella unfriendly and switch to something else. Once someone is familiar with Gnutella and starts to really like it, it's very likely that he starts sharing some content.

Do you think people without a homepage should not be able to browse the web?
