I was recently reading an article, and I came across the following text (emphasis mine):
Even that most notorious of “Communist” licenses often cited by paranoid executives as examples of anti-commercial aspects of open source, the GNU GPL version 2 or 3, is useless when it comes to prying open web applications written by Facebook, Google, Microsoft and Amazon. And let’s not forget how some of these very same vendors infiltrated the process of creating the GPL version 3, undermining the community and cutting off efforts to close the “web app loophole”. How they did that was an under-reported story from 2006–2007.
What are the details of this "under-reported story"? Searching on my preferred search engine and some Wikipedia reading comes up with nothing.
