And, I'm sure you know that IBOC was created (could have used FMeXtra)
to destroy community radio - right?

Actually, HD was developed nearly 20 years ago by what used to be Bell
Laboratories, and then merged with complementary technologies to create
iBiquity with the goal of finding an in-band digital solution for AM and FM
that would not upset the entire industry and which would bring digital to
radio just as it was coming to TV.

Community radio did not exist in 1990.
