You might be interested in reading up on the Loyalty Effect by Fredrick Reichheld (and associated books Loyalty Rules and other). He used to be a partner at Bain consulting but the premise of his books is that consumer loyalty has value and it's worth the time of organizations to measure and maximize that value...
He makes similar points you have that it doesn't make sense to charge new customers more than existing clients because existing clients add more value through things like referrals, they buy more services at lower cost, they no longer incur acquisition costs, etc. An example of trying the alternative would be places like my gym which happens to be a national chain - whose membership services I hate but I bought a while back and they don't up membership costs for old clients but they do for new ones. My membership costs probably about half that of new members because I joined a good 6-7 years ago which makes it rather unlikely that I'll ever give it up.
Personally I think the reliance and dependence of a lot of service companies like Comcast on the value of their infrastructure is a dangerous game given how much the cost of infrastructure has fallen and continues to fall.
The economics indicate that giving discounts to new customers is more NPV positive than just repricing the whole portfolio. Every portfolio has sleepy customers who don't get maximum value or the maximum perceived value. However, every active and vocal customer should be provided with all benefits. That's the perfect marriage of economics and customers service.
