Not all targeted advertising is bad. Would you try to stop a local high school fundraiser for intelligently reaching out to the community? Or your family's local small business from advertising to the audience most likely to want to shop there?

Targeted advertising in some shape or form has existed for a hundred years. Just open any magazine that is targeted at a specific audience and you'll see widely different ads running in those magazines. McDonalds or Coca-cola aren't going to waste ad dollars running campaigns in hunting or boating magazines for example.
