Since Kentucky backed off (And probably negotiated a clause preventing KFC from causing ridicule of the state and its liberal governor), that’s been KFC’s line. But the change was made before KFC introduced grilled chicken, but right after Kentucky started suing people for using its name, so I’m not buying it one bit.
By the way, KFC didn’t explain the name change until fans of Popeye’s started spreading the rumor that KFC no longer uses real chicken.
I see you got to this first.
The more extreme version of the myth was: You can’t call it chicken anymore once you cut the feet off.
