I guess that Everipedia will have to keep selling ads even after moving to EOS. Otherwise there would be no incentive to buy their tokens. The situation should be different from Steem: an encyclopedia is expected to be neutral, while Steem is made in such a way that the richer are also more influential. I can imagine an encyclopedia with some advertisements confined to the right places, but an encyclopedia following the logic of Steem... that seems nonsense to me. Was this question already answered?
