The whale vote on the Hive DAO (the DHF)'s return proposal was a hot topic with users of the protocol over the past couple of weeks. You see, a DAO (a Decentralized Autonomous Organization) by definition does not have a central entity that controls it. So mechanisms like the return proposal, or threshold proposal are used to determine which proposals in the DHF get funded and which don't. Anything with more votes than the return proposal gets funded and anything with less votes doesn't. As you can imagine, when the return proposal gets voted on with lots of HP, it's harder for a proposal the get funding as it will need more support from stakeholders.
