I guess I don’t think they are related. I could be wrong, but I think this type of dynamic happens a lot...years later, one, then another.
As for keeping it suppressed, I would think it is the usual celebrity thing, not a liberal machine being set loose on someone who steps out of line.
But as we have seen what the liberal machine did to people who went against the Clintons, or even further back, McCarthy...well, nothing is impossible.
I think the Savile case explained at #73 may be a close fit to Cosby.
Not as prolific, more selective (models etc), but a close fit.
