People are annoyed about it because it's stealing from the rest of us who do pay our taxes.
That's an interesting moral viewpoint!
EDIT: Perhaps I should put it more clearly...
If you sell goods on Google Play, I believe there is a fee of 30%. Now, imagine I found a bug in the Google Play store that meant that, even though I sold millions of copies of my app, I actually paid 0% to the Play Store. Do you think that Google would just accept that I'd found a bug in their software and therefore I owed them nothing? Do you think I owe them nothing?
Google chose to participate in a market where the costs were clearly labelled up-front and they didn't even have to pay a penny unless they made a significant profit!
Why the hell should they get away with paying nothing for a service that other people pay a lot of money for?
If not, then Google is to blame for taking advantage of tax loopholes.
* the software is designed by committee
* in the interest of greater acceptance, the committee solicits opinions of users for how to design the software
* some users need certain features, and the committee members are open to "suggestion"
* committee members have no issue with accepting suggestions without considering their impact
* committee members have no issue with accepting bribes in exchange for guarantees of certain features being implemented
* committee members actively solicit suggestions because they want money
* there are no repercussions for committee members taking bribes and blindly accepting feature requests, as a matter of fact it's official policy that they do so
Yeah, those "hackers" are definitely to blame here. They're playing the game by the rules and they're winning, and that makes you upset? Personally I'm not even surprised at all.
Man, the mental gymnastics people will go through to justify tax avoidance is astounding. Those with greater knowledge in an assumed non-adversarial system have a moral imperative to disseminate that knowledge to the others in the system. Otherwise taking advantage of the information imbalance and the other party's implied trust is unethical.
Just because something is legal does not make it right. Those who would outsource their moral thinking to laws are a sorry lot.
There are no mental gymnastics in determining how much taxes you have to pay, the only thing that matters is how much you pay.
Morals/ethics do have a determination whether the concept of tax is ethical or not, which would then determine the ethics of avoiding said tax. If you take the position that tax is ethical (as a member of a society...) then it is at least on the surface unethical to avoid the intended tax rate (shifting burden, freeloading, etc).
Also in a free market, governments should compete for companies to register their books in their respective countries and the competition between the governments should keep the tax rates fair.
