Are you going to ask why ESPN confines its coverage to sports?

Confining your coverage to a geographical region or industry or both is not the same as confining your coverage to companies who are willing to effectively bribe you, which is an ethical breach of the highest order.

Edit: Forgot to mention, you're completely misusing the word "embargo" here. It's a term of art in journalism. See http://en.wikipedia.org/wiki/News_embargo
