I've been voting with my wallet for a long time... Nobody seems to notice...
Oh, companies notice...and they pass the lost revenue off on the customers that are too stubborn to vote with their wallets. Eventually the prices will become too high for even those people justify keeping their service.
In theory anyways. Regardless if it will work or not, I am content saving my ever increasing amount of money every month for a service that is degrading more as time goes on.
Actually for those that "leave" often they go to another company due to promotions. Cord cutting isn't as popular as many claim. Even Telco TV customer gains are high. Those leaving cable go else where.
