If there's enough inactive accounts to be the deciding factor on a single proposal(these unlike witnesses do have expiration dates), others who have voted for the proposal might want to unvote if its not being met. 22 million HP is quite a bar to reach to start getting funded. And if a proposal is getting funded but its work is being met, then theres no problem with that, no matter where the votes come from. It's like autovoters on posts to me.
