"In absolute terms, GPL use has increased - any change isn't
down to GPL projects transitioning over to liberal licenses. But an
increasing number of new projects are being released under liberal
licenses. Why is that?
The impression gained from this is that the probability of you
using one of the GPL licenses is influenced by the community that
you're part of. And it's not a huge leap to believe that an
increasing number of developers are targeting the web, and the web
development community has never been especially attached to the
GPL. It's not hard to see why - the benefits of the GPL vanish
pretty much entirely when you're never actually obliged to
distribute the code, and while Affero attempts to compensate from
that it also constrains your UI and deployment model.
