In the long term, I think the positive effects of sharing with the developer community will outweigh the negative effects of copycats. Sure, it's a little disappointing to see someone else using your ideas. But I'd much rather this scenario (where everyone can copy, be inspired, or even steal freely), rather than a patent-ridden ecosystem where you can't take inspiration from anywhere, for fear of being sued.
So at the end of the day - no, I don't feel the same way. I understand the position Chris took with kreci.net, but for my part I just take the copycats as an indication that we're still living in a free marketplace :)
