You're acting like the people posting here don't know that about theories. Language works within contexts, and the context for "confirm" in science reporting tends to be finding strong supporting evidence. Since the discovery of the CMB ruled out a large chunk of the other theories and left the Big Bang as the leading candidate, it obviously fits the finding strong supporting evidence case. We see similar titles every once in a while when someone does a new kind of test for relativity too.
