Hidden Sponsor?

Why is everyone so thankful to Oprah today? I don't get it. For those of you not aware on yesterday's episode Oprah announced she was giving away chicken (by way of a downloadable coupon)

All the interviews today of local people are people THANKING Oprah! Why?!? She is clearly getting paid by KFC! This is a purely sponsored event to sell KFC's chicken. Why are people pretending this is something other than a giant COMMERCIAL.

The news coverage, the online coverage and the radio coverage are all free advertising for KFC's grilled chicken (though I am sure it wasn't completely free given the amount they had to pay Oprah).The link the coupon is below if you are dying for grilled chicken:
