So does it matter whether this proposal gets approved or not?
Yes you should vote for the plan, it matters. If you go read the proposal you will see a listing of estimated recoveries they expect to get that total several million dollars on top of the cash they have on hand right now. The company had a 3 million dollar insurance policy for example. They are also in the process of suing Cypherdoc to recover 3000 BTC plus a few other things.
I'm not certain that the decision was as cut and dry as that. Ask yourself, "who continues to profit if we vote Yes?"
