I do respect RMS, but there is a sitcom contained in these two lines.
Many of his arguments are strong and worthy of discussion, even if his overall stance is not always so - but the way he expresses them can border into childishness sometimes. It's a pity; it gives his detractors (of whom I am not one, to be clear) an excuse to dismiss him.
But his way of communicating often leads to an initial impulse to dismiss what he is saying outright, much like I would dismiss a Microsoft criticism which referred to the company as M$ or an Apple criticism that kept calling it crApple.
That quote however made me exhale rapidly through my nose, and I was still chewing on some spaghetti at that point resulting in little pieces of spaghetti ending up in my nose. Totally not a recommended experience. I can't help but still consider RMS somewhat nuts.
(I have a lot of relatives who worked for the government and I was a military wife for a lot of years. This is a problem I personally wrestle with and it is likely a factor in my persistent poverty. So it isn't intended to insult anyone.)
