Your implication is that RMS was spending that money on himself for luxuries.

Are you sure the money wasn't being charged by his foundations (or given indirectly - e.g. used for his living expenses)?

Hard to know what his intentions were unless there's a link to something where he explains himself e.g. he could easily just be valuing opportunity costs.

I didn't specify or imply what he spent the money on, only that he demanded compensation for his time and energy, and at quite a hefty (well-deserved) price. Whether he did that as himself or under GNU Project or FSF auspices is also immaterial for purposes of this discussion. People both for and against open source seem to believe there's an implication that developers' time is free as well, and I'm just showing that the most dogmatic advocate for free software of all believed otherwise and put those beliefs into action.
