I agree with your first point, but your second point doesn't follow. If anything, Comcast will price gouge Netflix out of business, and we'll be back to being stuck watching their awful "On Demand" instead.
They can do this, because Comcast owns the content (NBC), the delivery mechanism for said content (cable TV), and the only delivery mechanism (broadband Internet) for their competitor (Netflix/Amazon Prime).
On the other hand, the (failed) merger attempt between AT&T and T-Mobile was the best thing to happen to consumers in a long time, due to the breakup fee that AT&T had o pay T-Mobile($1+ billion worth of spectrum).
I'm trying to imagine a similar silver lining that could happen here, though I can't think of any.
