> I'm just bemoaning the larger context of copyleft non-adoption. I rarely bother to use copyleft for my personal open source work, because I'm not typically interested in hiring lawyers to try to enforce compliance. And if I wouldn't pay a lawyer to go after a violator, then I don't personally see much point in using anything more complicated than CC0 or a boring permissive license. Licensing adds overhead. If I use the GPL, then somebody has to stop and ask themselves, "Hey, can I use reuse 30 lines of this GPLed code in this MIT-licensed project? Do I need to change my project's license? Do I need to ask permission?" Usually I don't care. However, for certain projects, I am perfectly willing to enforce a copyleft license. In that case, I'm happy to use the GPL 3. It's a good license, and I'm very glad it exists. I don't feel like anybody else should feel obligated to take my approach. Part of my philosophy here comes from painful personal experience that successfully commercializing code requires years of sacrifice, and 99% of what I write in my free time will never be worth that effort.
