Boycotts can take on different levels. I'd personally say that if you already own an iPhone, Android phone, Mac or PC, you've already given them your money, but you can absolutely refuse to give more the next time around and buy something from another manufacturer that's not US based. But it doesn't make sense to just throw out your perfectly fine $1000+ device just to "stick it to the man."
