This kind of attitude isn't logical and is in fact extremely dangerous. It's the same argument as "if you don't have anything to hide, why do you mind being spied on by corporations and governments?"
It is entirely reasonable and in fact GOOD that people have strong opinions about things even if they do not personally interact or care about the actual thing. When an increasingly large amount of our society is shaped by Apple or Facebook or Google, their decisions affect everyone, even those not directly using those services or being customers.
Opinions matter. Don't tell people that they should shut up and ignore global implications because they themselves wouldn't buy the product.
