If Samsung worded it "We're donating $500k to support the great work the Linux Foundation does with FOSS" then I might give them a nod. But to say they are investing $500k (a paltry sum) to battle iOS is kind of sad. Why even say that, it sounds so petty.
So your only motivation is to attack Apple? It's not to simply support the legion of open source developers that have been giving you free software for years?
