Ambivalence

I have several questions.

1. Why was I compelled to buy this? 
2. Why does this label make me believe a drink that's mostly sugar is cool?
3. Why would Pepsi want to advertise that they usually use unreal sugar?
4. Why would Pepsi want to advertise that they will return to using unreal sugar?
5. Is "Throwback" what happens to you when you gain 40 pounds because you drink sugar water and then try to lift something without stretching?
6. Why was I compelled to buy this?
