Don't be daft, Samsung are the suppliers because they gave the best price.
Samsung will also be locked into supply contracts anyway, and they interfered with them, Samsung would be in a world of hurt, not just from Apple and litigation, but every other company they supply.
And don't you believe there aren't alternatives for Apples component supplies either - every company that can build something that Samsung already does has been on the phone this week to Apple.
The end result in all of this is that Samsung are putting at risk an $8bn turnover for copying a customers phone design.
Even if Samsung win any of these suits, Samsung will lose the $8bn turnover, and will hand their component rivals the same amount.
The question at the end of the day is whether the Galaxy/Tab/S/S2 are really worth $8bn a year - which they aren't.
So who loses? Samsung every time.
Heres the clue - never sue your customer.
