The idea is that cooperatives don't have to treat everyone exactly the same. You can have different "classes" of members. You can have ordinary worker members, but also "founder" members. For example, for an agreed number of years "founder" members can get to elect a certain amount of board seats and get a higher share of profits.
Sure, it moves away from "one-person one-vote" democracy and full equality, but only for a temporary period, and it still gives ordinary workers a much greater say in their workplace than they get in standard companies.
