GNU is awesome in the way that 'Citizen Kane' is awesome. It is awesome because of what it accomplished given the context in which it was created. The context has changed but GNU, by and large, has not. "Free Software" gave us BSD and Linux, but it is also partially responsible for the privacy issues of Google and Facebook (neither of which would be as competitive if they had to pay licensing fees to Microsoft and Oracle, and they give their services away in exchange for monetizing user data), Heartbleed and similar bugs (these projects are not properly funded for security audits and/or maintenance), and the expectation that one should work for free (if you don't have a job the first thing you do is start working on open source projects to show what you can do). Richard Stallman is arguing for the freedom of software, not people. Unless we change society such that its citizens will be provided for regardless of how they spend their afternoons open source needs a new business model. As software becomes more pervasive finding alternative models will become more urgent. And, it's already very urgent.
Thought experiment: if there was no GPLv2, only GPLv3, would the same concerns apply?
Have you come across promising alternative models? These would need to exhibit some properties of GNU-style free software and some properties of cash-cow commercial software. Thus, technical run-time mechanisms for software composition will play a key role in the new legal framework, just as linking (e.g. GPL vs LGPL) did in the GNU ecosystem.
Today we have microservices, containers, etc - which allow composition of software with different licenses, T&C and biz models.
