He sounds like some random person spewing random subjective opinions about things, rather than the original author of GNU Emacs making an honest effort to provide leadership and guidance that means something (anything) to anyone other than himself. He sounds helpless and oblivious to everything and everyone except his own personal proclivities, which is the opposite of leadership and the opposite of an experienced person providing valuable guidance to the community. Like he's not even making a token effort to do those things, and to say he's metaphorically lifting a finger here to provide leadership and guidance would be very generous.
This is akin to Linus rejecting a driver because he doesn't own the hardware, or because he doesn't like the colors of logo of the company that makes it. It really doesn't get more incurious and intellectually/emotionally immature than that.
This is in 2020, after a couple decades of Emacs being one of the only actual software projects he involves himself in anymore. To be clear, I've had a really low opinion of RMS for going on 20 years now (after a few years in college where I thought he was cool because I didn't know any better and people seemed to revere him because they thought everyone else revered him). But reading these mailing list exchanges are still kind of shocking to me. It's really hard to believe that anyone on the GNU mailing lists pay any attention to him at all, or values his opinion on anything. For those that do, surely that's nothing more than a cult of personality, it just seems as plain as day to me. This is exactly the sort of thing that drives people away from GNU and the FSF, and it sucks because they could be so much more impactful and meaningful and helpful and positive and constructive otherwise.
Sometimes I think if more people had simply stopped making excuses for RMS like 20 years ago, we might currently be living in some sort of GNU utopia dreamworld where everyone everywhere uses Emacs for everything, and GCC is the preeminent compiler suite, etc. etc. etc. It's quite a high cost for people to pay, when the only thing they get in return for keeping this guy around is helping a damaged narcissist continue to feel good about himself and continue alienating everyone else, just like he's been doing for decades. He absolutely got GNU and the FSF off the ground and helped create a large community that has produced tons of great software, but in the past 25 years it seems like all of his efforts have been counterproductive to his own goals.
