I think we're all overlooking the fact that Charlie did not say Dish and DTV SHOULD merge, instead he said that a merger was "inevitable". Typical of CCN, their headline is a little more dramatic than the facts.
To me, the word "inevitable" seems much stronger, or more dramatic, than CCN's title stating that Charlie "thinks" they "should merge". Charlie is saying that the eventual combo of DISH and DirecTV seems like it WILL happen at some point, that it's unavoidable.
