It was obviously a joke and I seriously doubt anyone would be offended by that. I know I'm not and I'm relatively understanding about the austerity measures.
You'd have to point me at something that would suggest it was said in jest then, since I don't see anything that would support that assertion.
Frankly, there's a reason why I used the word 'appreciate' rather than 'respect' and that's because while RMS has done much good for the world, he's also an extremist and a fundamentalist who's publicly held convictions in some areas indirectly damage the cause he's fighting for.
