Newsweek = Treason?

today on my way to work i was stopped at a light behind a suburu outback. the driver of this automobile was approximately 50 years of age. i couldn't help by notice his homemade "bumper sticker" taped to the inside of his back window. it said "Newsweek = Treason". This made me go to the newsweek website to see if i could find anything that could be considered treason. After an extensive search through recent articles i couldn't find anything.
