What journalists often seem to confuse is that fruit sugars eaten as whole fruit tend to be fine because the amount of sugar you can reasonably eat is quite limited (you're not going to eat 10 apples or oranges), and the sugars are bound up with fiber so are slower to digest, so "fruit sugars" are generically considered to be "fine".
Unfortunately that falls on its face when you're talking about juice. Almost nobody is going to eat 8 medium oranges in one sitting, but you might easily drink the resulting 16 oz of juice they produce. In that case it's little different from a Snickers candy bar.
