That was indeed a really interesting read! It really made me think more deeply about software licencing. I didn't quite understand what the authors problem with GPLv3 was though? That the companies are scared of it? Isn't that kind of a good thing? I don't want amazon to make massive profits off of my work, because if that's possible to do, then that would necessarily mean, that my goal as a developer (to protect my work from exploitation while helping the common good) isn't working. I am curious what you have taken away from the essay though? How do you protect your code from corporate exploitation?
