Your original claim concerned moral philosophy, but the evidence you provide in your latest comment predominantly concerns political philosophy. Consequentialism (a moral view) is compatible with liberalism (a political view), so evidence for the popularity of liberalism is not itself evidence for the unpopularity of consequentialism.
Furthermore, a representative poll where professional philosophers can state their preferred moral views directly seems to be a better measure of the relative popularity of those views in the philosophy profession than citation counts of books published over a given time period. The latter may be relied upon as an imperfect proxy for the former in the absence of poll data, but their evidential relevance diminishes considerably once such data becomes available.
Note, too, that using your criterion we should conclude that falsificationism—advocated in Conjectures and Refutations and Scientific Knowledge—is the dominant position in philosophy of science, when it is in fact moribund. Similarly, that ranking would misleadingly suggest that eliminative materialism—advocated in Consciousness Explained—is the dominant view in philosophy of mind, when this isn’t at all the case. In fact, many if not most of the books cited in that ranking represent positions that have largely fallen out of favor in contemporary analytic philosophy; this is at least the case with Kuhn, MacIntyre, Ryle, Rorty, Searle and maybe Fodor, besides Popper and Dennett. In addition, owing to discrepancies in the number of philosophers who work in different philosophical areas and the popularity of some of these areas in disciplines outside philosophy, the poll grossly overrepresents some areas (political philosophy, philosophy of science, philosophy of mind) and underrepresents others of at least comparable importance (metaphysics, epistemology, normative ethics), strongly suggesting that it is particularly ill-suited for comparisons spanning multiple areas (such as one involving both normative ethics and political philosophy) and further strengthening the case for relying on poll data over citation counts.
Let me however highlight that I agree with you that the high prevalence of consequentialists in the EA movement is a striking fact that raises various concerns and certainly deserves further thought and study.
