I used to make so much fun of RMS in the late 90s. Then I met him and my entire view on that man changed. He absolutely is doing the world a favor and it would benefit everyone to think long and hard what a world would be like without GNU today
You have of course given no idea of which people you're objecting to. But the people I know who were upset at Stallman a few years ago had clear, specific concerns, and some of them were directly harmed by Stallman.
If you would like to rebut their complaints, feel free to give it a go. Or you could also claim that the harm caused was justified or excusable given the positive things he's done. But you have to actually make the case, rather than just smearing them like this.
I feel like the refusal to close the network hole in the GPLv3 is a significant blind spot of his, and is a decision that has aged incredibly poorly in the age of cloud services.
