What is or is not 'overpriced' or not is strictly a matter of opinion. And there is enough testimony out there to support either argument in the case of sportspacks, so it honestly doesn't make much sense to debate that issue further...
With regardes to both providers essentially charging the same for their base packages, why wouldn't they? The D* sportspacks have a wide enough subscriber base to support themselves whereas if E* were to start offering them, they would be starting out from zero, and its doubtful that E* is in any position financially at this point to sustain any loss in the interim. Charlie would more than likely raise the rates just as he has done so in the past, just to cover his potential losses.
I thaught I made that clear. Sorry about that.
