Competitive landscape has changed a lot since then. A Dish/DTV deal is highly possible and would not be anti competitive. You have streaming services etc which are threatening Sat and cable plus the mobile operators are pretty dominant in their own right. Not a problem getting past the Justice department.
That was years and years ago... The fact that Dish is still growing is the very reason that DTV wants them and will pay up for Dish. SEC won't block it in today's environment, things have changed drastically since then. Finally, at the right price Charlie will have to sell.
