A few years ago I saw an indie game developer recount his experience with Stallman[1]; he doesn't see how he can release his games as Free Software while making a living, pay his rent, pay for his children's education, etc. So he asked Stallman what to do about that.
Stallman's reply? "You should not be making those games, it is unethical."
To say that is non-constructive would be an understatement; it's just shutting down any conversation and exploration and how we can improve things. There are a whole bunch of things one can think of: release the code but keep the assets (graphics, sound, music, etc.) proprietary, release under some sort of "source available" license, keep the core rendering parts proprietary SO/DLLs and release the rest as free software, and maybe a few other things. All of that would be a huge improvement over "100% closed".
But Stallman isn't open to any of that, and because the FSF is still very much Stallman's organisation, neither is the FSF. For at least 20 years the FSF has done nothing except preaching to the choir, and certainly hasn't actually made many significant meaningful every-day improvements. In the above situation the game dev essentially asked was "what is the best way to make my software more free?" and all he got was a rather insulting and condensing shutdown of that conversation before it could even take off.
