I really hope other GNU projects, in particular Emacs, follow suit, though I doubt it will happen.<p>In my experience it is a massive hassle to get the copyright disclaimer from my employers. I'm currently on hold from contributing to Emacs because my paperwork is working its way through the legal bureuacracy of my new employer. Also, I have former coworkers from previous companies who were enthusiastic about Emacs, but unwilling to go through the trouble of getting the paperwork to contribute.<p>I think getting this paperwork through is probably more difficult in my industry, than in others -- I do R&D at a large pharmaceutical.<p>Still, I think the copyright disclaimer is one of the biggest factors that is limiting the number and diversity of Emacs contributors. I also think it's unnecessary, as Linux does not have this requirement, and it has successfully enforced the GPL, for example on router manufacturers.
