The RMS rider is full of lecturing and childish demands. I'm amazed people are applauding him for it.
He has codified his behavior expectations. If someone didn't know RMS was particular, they weren't paying attention.
They are no more demands than a request for him to speak somewhere is a demand.
Someone asks if he is willing to travel and speak to their audience, he says "yes though only if these conditions are met", and the someone then has a free choice of whether to continue or not.
A childish demand would be "we can't agree to X, but we expect you to come and talk anyway".
