Whilst the mooted increases may not be much, :
1) That's for now. Nothing stopping them increasing them at any point, on a whim. Basically, they will keep increasing them to a point where the profit from doing so is eclipsed by the lost revenue of falling domains.
No doubt they'll test the water with incremental changes, but they aren't the sort of people you want potentially holding you to ranson.
2) It's the damn principle! :-)
Biting the hand that feeds IT
