Been New on crypto and hive, I have a little knowledge on this, so I can only talk on the possible danger of adding beneficiary and getting a vote.
As much as some projects do the beneficiary stuff with positive intentions, the result may turn out to harm both the user and hive platform while the project benefits. Users may start posting without critical thoughts, under duress of gaining rewards, their dedication will be channel on reward above other concerns, and giving no room for personal growth- something I enjoy most about hive.
Quality in creating contents will reduce as more people start to subscribe to that initiative, thereby affecting the hive blockchain either directly or indirectly.
But looking at this, there's a community I believe use the beneficiary thing effectively because it gives back to the users @lmac community. It liquidate the stake hive and give back to the users, and it encourages quality.
So, I suggest a balance should be created when taking decision on this subject, and if necessary, delegation should be fine to complement that space.
