Because the ABC and BOM have experts who are also enthusiasts.
As much fun it is to criticise the BOM when it is 34 degrees and rainy when they said it would be 33 and sunny, they are still the most accurate source of weather information.
The ABC (and independent public radio/TV) only interest is (should be) serving their communities. The ABC does have to satisfy their political and corporate overlords (look at what Arnold Frollows did to JJJ) but is a more reliable source of reality-based news and information.
When the ABC (and RRR/PBS/MBS/etc) stuff up and get to “corporate”, they loose supporters. Think of what happened when Sportsgirl tried to become a RRR sponsor…
Frollows fired Tony Biggs after he played NWA on air.
He is immortalised in the song “Arnold Frollows is a Genius” by Front End Loader, which was a sarcastic criticism of him.
