It can be done, but for some it's easier as for others.
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.
Targetting is not a bad thing when done right.
Wow, OP really feels his friends chose Google over the friendship?
HN ought to weed duplicates better.
