Free Software is not about slavish compliance with licensing terms or inventing shiny new technology for technology's sake (that movement is called Open Source). Free Software is about having the freedom to control your computing environment.
I believe this is really, really important because in a world increasingly shaped and even dominated by technology, people have to be able to look under the hood and fix the code that runs their society. Otherwise they become slaves to whoever made the rules by writing the code.
Proprietary software violates this requirement, but at least you can reverse engineer it, hack it. With cloud services, even that option is removed. The user has lost all control. This is pretty obviously bad for a democratic society, but hey, it's great for tech wizards aspiring to be the next Mark Zuckeberg, so who cares about that? :-P
