I eschew free software because I'm not about forcing my views on others (which is literally the mission of GNU). I'm about developing software to be the best it can be, and maybe meeting some friends along the way. Open source, being the best software development model overall, allows me to meet that goal. You could almost say some of RMS's more extreme quirks border on authoritarian (see the example with the abortion joke in the libc manual he FORBADE removal of and demanded be re-added when a dev simply overruled him). He's not acting in a manner that encourages "freedom", but as a simple and obvious dictator of all things GNU or claiming to be GNU. He's frequently tried to shape the path of GNOME (which I am a former foundation member and was on the sysadmin team) in areas he literally has no business weighing in on. Then there are some more gross personality problems, like his sexism, or tendency to actually eat his toenail gunk, or to ever refuse to be wrong on anything, even when an entire community disagrees with him.
Dr Stallman has done a great deal of good for the world with Free Software, however like the VAX and PDP-11, his time has passed. Open source won just like Linux won over GNU/Hurd. It is ok that he won, by losing.
In the context of GP's (beginningguava) comment about 'open source projects' needing to change their licensing to prevent corporations making money by SaaSing various tools, my point was twofold - first, by definition you can't have free software with restrictions like that, and second you'd be merely fighting the symptoms (with little chance of success).
Aside - I'm curious what you mean by the 'open source software development model', as I don't think that's actually a thing.
It goes back to ESR's The Cathedral and the Bazaar and is what he deems "the bazaar model" or "bazaar style" before him, Larry Augustin, and Bruce Perens (if memory serves) went on to coin the phrase "open source". Even if you don't necessarily agree with ESR (I see him in a similar vein as RMS fwiw), his thoughts on software development models have generally speaking, been proven true.
