It's especially troubling because this is yet another breach of privacy on their part. People liking pages or apps don't expect to be spokespeople for these companies, so showing my name next to an advertisement is disingenuous. It's made even worse that this is opt-out, and my name is displayed on sites other than Facebook[1].
There is going to be hundreds of millions of people who will never even know that they're recommending products to people, and that's bad.
