The SPS.DAO is owned by all of us who stake SPS. The APR that the DAO would be "taking away" would be going into a fund that you have the same percentage ownership of and control over as what the DAO would be "taking away".
This proposal doesn't decide what the DAO would do with the GLX in the future. The important part for the future is that the DAO maximize its yield with the assets it has so that we have a funding structure for future rewards.
RE: SPS Proposal - SPS.DAO should stake an additional 28,000,000 SPS for a total of 30,000,000 SPS
