When you have high expectations and they are not met (or sometimes even just have the appearance of not being met) that feels a lot worse than when you have low expectations which are met.

Hence if Google does something even close to being interpreted as being evil if you squint hard enough, they are ditched in favour of Facebook. If workers on iPhone production lines have tough working conditions, even if they're better than the working conditions on the Samsung lines and are better paid, you still get people swearing to buy a Galaxy next instead.

It's just human nature.
