Great that you have a post grad math degree... now go back and get a business degree so that you understand that Apple (and every other US Based international company) does what Apple does to not get double taxed and over taxed. You do understand that it's profits they made outside of the country, that are already taxed by other countries, that will be taxed again by the US if they bring it back? The problem is not Apple... it's bad business tax policy by the US that forces smart companies to do this.
Also, on encryption. We have survived on the current security? Maybe you should Google the current stats on cyber crime? It's hardly working now and I believe the biggest threat we have is cyber attacks by radical groups. Better and more security is not a bad thing and if Apple can deliver and profit from it, more power to them.
