The bigger your footprint becomes in the arena of the Internet, the more care it takes to make sure you are not stepping on other's IP. The problem with the Interwebs is that IP crosses so many silos and this isn't just a problem of name but of application of the use here. I can't see FB being more than apologetic to FiftyThree. As much as FiftyThree thinks they have just cause here - its more of a use / intention than it is the confusion with name. I highly doubt anything will come of this, because of the logical difference. Its an identity thing vs. market clash over the same product.
