FCC Chair Stands by Proposal to Limit AT&T and Verizon

It's a fair question, and I would argue that Sprint is still at a disadvantage due to the IBEZ limitations on the use of its spectrum. They're also the only carrier with SMR spectrum, whereas 600MHz spectrum will end up as a roaming option for likely several carriers, and the SMR spectrum Sprint has is very limited (something like 12MHz).

Maybe it's because it's such a small chunk that it doesn't really count. I don't think they can do much with it.
