It's an admission that Jimmy gathu's "Wacha mpango wa kando" message landed on deaf ears! People didn't change.
Or perhaps it was a natural progression through the A B C of fighting AIDS.
A = Abstain (remember "Nime chill" adverts)
B = Be faithful (Jimmy Gathu's ads)
C = Condom (Now we are here)
Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
