Yeah. I personally think that offering the donations only survey was a bad idea for the reason that you said and a few other reasons.
Even if everyone took the full survey, the non-response would still be pretty non-random—you still have to have the tenacity to persist to page seven, which I imagine correlates with being more involved in EA and you also have to have taken the survey in the first place, which we also know is not random. It would have been nice to not make this worse, though.
