Sometimes it cuts both ways. Greg Notess mentions that small chunks of data such as stock prices, sports scores, and weather reports fit well onto the small screen of a mobile phone using WAP while full articles do not.

Magazine articles provided at no charge through publishers' Web sites carry a price tag elsewhere online.
