It's probably not the end of RT, though I kind of wish it was. Not because of the drama, but just because the content isn't that entertaining. Sure, I've grown up and my humour has changed, but they've changed, too. In hindsight, we can kind of pinpoint the shift in quality when Full Screen bought them out. Some people are taking time off. I don't know how many people can take time off camera.
On a more degenerate note, what if Barb left RT and went all in on OF? I think she'd still do what she's doing, but be more active. I don't expect nudes, but still the occasional lewds.
