There are good and bad redesigns and there's hyperbole. Most of Windows/Facebook/iOS outcries are hyperbole. Reddit's new design is just bad. For a good example of a slick modern redesign look at new Gmail.
Right, agreed, the Reddit redesign is just bad. But the fact that probably 99+% of any UI/UX changes result in an uproarious outcry from users, even when it's not bad, probably results in these outcries simply being ignored.
