Google, Motorola and Samsung didn't start trying to use FRAND patents until they had to defend themselves from Apple's onslaught.
No doubt there are tens of thousands of other lawsuits in progress, most of which are from non-practising entities. Regardless of the value or validity of Apple's patents, at least they are actually making real products that utililize them.
As for the design patents, I'm sorry, but anyone that can't actually read and distinguish the words Samsung and Apple on the box or on the device itself, has no one to blame but themselves for any confusion that resulted in buying the right product.
Judge Richard Posner put it best in his dismissal of the Apple-Motorola suit. Regardless of the validity or not of the patents, neither side could actually prove any actual damage and given Apple's capturing of 80% of the profit in the smartphone business, it doesn't appear they have actually suffered even if other companies have infringed.
