A couple of points here, in no particular order:
1. Apple is a corporation, a corporation whose sole fiduciary duty is to its shareholders. Not you or me (unless we're shareholders) or any other entity. Apple is only doing, and doing spectacularly well, what every corporation with good financial management tries to do. Maximize profits. Minimize expenses. Taxes are an expense.
2. We have romantic notions about this corporation because we seem to form emotional bonds with their products - probably a bit ridiculous when examined closely. For years, we long-time Mac users were a small(er), exclusive club; we enjoyed that camaraderie - the feeling of superiority that WE had the keys to the kingdom (computers that just worked!) while the rest of the world cursed their lowly PCs. The fact that the company whose products we championed struggled only added to the romance. Obviously, one glance around a North American university classroom or airport waiting area today will disabuse anyone of the notion that Mac owners are all that unique now.
3. Nobody can be bothered kicking (or writing stories about) a company that is just one of many, doing ok. Those, like Apple, flying high and the former high flyers are good story fodder for those wanting to sell newspapers. Moral outrage - even if ridiculously misplaced, sells. Envy of success...gloating over another's supposedly deserved misery. Not pretty, but very human, apparently. Angels one day, demons the next.
Generally, I'd suggest that the jurisdictions in which Apple is doing business only have themselves to blame IF they're not happy with the corporate tax structure and what companies such as Apple end up paying in taxes. Many states and countries twist themselves into pretzels trying to attract more corporate investment in the blind belief that no matter how they manage to do it, it will benefit the state or country. Complaining about it after the fact is nothing more than whining.
The tax structure in many countries protects those LEAST in need of the protection, which is hardly surprising when you consider where the power rests. Changing it requires a tremendous act of political will, fuelled by a cultural change I simply don't see happening any time soon in the US or most western democracies. Wall Street protesters have a problem - lots of complaints, but not a lot of solutions - or certainly not solutions that those in power will ever endorse, which combined with a general lack of interest/deep understanding of anything political or economic in the general populace dooms them to being a fringe element. I could say more - much more, but I'd be in a TS no-go zone, so I'll stop there.
Now repeat after me: Apple is a company. Apple exists to make money for its shareholders. Apple is not a philanthropic organization dedicated to the betterment of the human condition. Neither is Microsoft, Walmart, Google, General Motors or Intel. Some companies are better "citizens" than others (and some just better at publicizing it) - but NONE of them, unless badly managed, pay any more taxes than they have to.
