My answer is less useful to the discussion. But here you go: 1. I wouldn't use GPLv3 2. I wouldn't care if people stole my code that I open sourced or if they tried to license it a different way. 3. I personally follow the license of others when using their code. I wouldn't steal GPLv3 code without proper attribution etc. That's their right. All that doesn't go against my initial opinion: GPLv3 for a small micro blog templating system is lame. Enforcing it for a bit of CSS is petty.
