Isn't this 'Vote with your wallet'? I know I vote with my wallet. Everything I buy is a vote for how I want the world to be, and what products I want to see flourish and prosper. I also evangelize these products to others so they get on board too, because I alone will not make much of a dent, unless I recruit others to purchase it too.
You choosing to buy from Apple instead of Samsung will sure have an impact on the world, but probably not how you think it will, not what will be marketed, and more in the line of which lobby Apple chooses to pay with your money down the line.
