I think Stallman is fantastic; I couldn't care less about Gruber. I actually found the rider thing oddly fascinating and not at all crazy -- I actually read through the entire thing in a single sitting, but I still laughed involuntarily when I looked at The Stallman Dialogues (the "mock" site):
Friendly conference organizer: I'm happy to have you stay at my house, Mr. Stallman. I hope you find the couch comfortable, I vacuumed all the cat hair off of it. And here, let me get you a fresh set of sheets.
Stallman: Thank you. I like this much more than staying in a hotel.
Friendly conference organizer: Great!
Stallman: It's a bit warm in here, though.
Friendly conference organizer: Is it? I guess I'm used to it.
Stallman: Above 72 fahrenheit (22 centigrade) I find sleeping quite difficult.
Friendly conference organizer: Well... I'll see if I have a fan?
Stallman: If the air is dry, I can stand 23 degrees.
Friendly conference organizer: I don't know if I have a dehumidifier. I'll go grab our fan...
Stallman: Thank you. A strong electric fan blowing on me enables me to sleep.
