Re: Such a negative spin. Customers with private modems are now subsidizing those without, as they are not costing Charter anything extra but are still paying the same monthly fee as those that require a leased modem.
Anyone who recently upgraded to a D3 modem on their own dime (~$100) really got the shank, as they could have waited and gotten a "free" upgrade from Charter. Charter should probably start a buyback program because these users might as well sell their modems on eBay (and opt-in to Charter's "free" one) and at least recover some of their money.
Overall I do think Charter made a good decision to simplify their billing and support by doing this, but don't pretend that there aren't any losers.
