To actually answer: Huffman's argument is that mods are like business executives and users are like shareholders, and therefore the users should be able to vote out moderators who are not acting in the users' best interests. He said this while also implying that the blackout was only supported by moderators, not by the regular users, and that this means that Reddit administration is having to step in to save the users from the evil, sinister "inactive" moderators who enacted the protest. Since Huffman thinks moderators should be able to be voted out by users because the users are the primary "shareholders" of Reddit, the parent comment to yours is asking (rhetorically) whether they will extend those policies to the CEO and other administrators.
