AT&T May Charge App Makers for Consumer Data Use

"..AT&T is working on a new service offering for application developers that, in effect, would charge the developer for the network data consumed by AT&T's wireless customers. The idea is to help application developers (specifically those that require heavy use of data networks) convince more users to sign up for their services."

seriously, can someone explain to me, HOW IS CHARGING THE DEVELOPER FOR NETWORK DATA CONSUMED BY CUST going to convince more users to sign-up for their service?

when your'e going to start charging app makers, the end-result is they might pass the charge to the consumers who use these apps.. so this might result in free apps getting chargers.AND might limit the signing-up too.

the way it was worded, it seems that this is done in good intentions, so did i misunderstood something?
