I think it’s reasonably likely that people earning $1m /​ year are systematically less inclined to bother with the survey, so I would be cautious about using the community response rate to extrapolate.
(On the other hand, 2000 is 5% of 40000, not 10000)

That is why I left quite large margins for error, one of which you note, the other being that those 6 were only earning 1m+, not donating.
