they're rescinding all CURRENT ones so that you have to reapply, and actually meet the criteria of a disabled archer to be able to use a crossbow. It's free to get one, it only takes a doctors certification (which if you are truly disabled shouldn't be too hard to get) then you're good.
EDIT: It's not free, its $13 per year. If you're going to bitch about $13/year then you probably can't afford to hunt anyways... especially not with a crossbow. Have you seen how expensive bolts are?
