Note that Steve Jobs' annual salary is $1 USD. Note that he's also donated heavily to other charities and organizations. Note that it's none of your business what anyone does with their money. Note that you're not contributing a dime to a new hospital. Note that is says 550 million will be contributed by the tech firms, and also note that you don't have a clue as to how much Apple will donate, and that you don't know what you're talking about.
And to the people complaining about Apple getting the publicity out of this over the other companies, think of it from a journalists point of view for a second. Don't you think an article with Apple in the title will get more views than one about IBM, Ebay, etc? They aren't going to give a slightly more accurate title to lose hundreds or thousands of reads.
Wait, I'm bringing logic into an Apple thread, forgot where I was, sorry.
