From a reader:

“The suits” understand that the marketing bogeyman of “cannibalism” is flawed, and usually the result of the preexisting unit/division reacting defensively to a new idea. A multichannel strategy ultimately increases overall revenue to the firm…the key metric is revenue per individual. For example, several retail chains with a catalogue and physical store channels who added an internet option have seen increased revenue for all three. People tend to buy more when there are more “interfaces” from which to buy.

And other way to put it is, subscribe or the suits will twist my little rigoletto — as Oscar Madison might say.
