I will defer to the Aussies or others better qualified than myself to determine if the RC has any teeth.
That said, there is no question that the coverage has attention. The frequency and intensity of pressure the organization is receiving from many sources, on many fronts, amounts to a long, slow death of a thousand cuts.
Someone mentioned on another thread about JWs becoming more "culty". This is a sign of itself of cognitive dissonance being experienced by the masses, in aggregate. CD is the product of internal mental conflict, and when these types of stories hit the media, the JWs' reaction initially is shock, almost immediately followed by a strong sense of denial. That denial is their "protection" from information they find very discomforting, and their response to the dissonant information heard.
All of this leads to a polarization of currently open minded people vs. hardcore adherents over time. The ones left who are "culty" in their behaviors are the more hardcore types, however being hardcore is not 100% mutually exclusive with being intelligent. Once something happens to them personally that makes them question, all of these accounts that caused CD come rushing back, and this time serve to confirm their doubts, rather than causing them to dig their heels in deeper.
If most of us take the time to reflect on our exit out, we can probably see how some variation of this process happened to ourselves.
