It's very telling that the word copyleft hasn't appeared in this thread nor in the submitted article.
I use the AGPLv3 for most of my software and it's a feature that large corporations horrified of contributing back fear it. I'm not exploited, because I use a license that doesn't allow me to be exploited.
No one using a permissive license, which are pushed primarily by corporations that slander the GPL I think, has any right to complain about being exploited, in my opinion. Copyleft is good and copyleft software still gets paid support and other things; as many companies have found, it's also a good means to release Free Software that people will still pay for, in the form of license exceptions, even.
