I hope this isn't feeding a troll. But here goes anyway...lose what customers? If AT&T stand by the current pricing, the existing contracted customers will either pay up to exit their contract (neither win, AT&T lose their monthly payments, customer loses up-front money) or continue to the end and don't sign up for a new contract (not likely).
Second scenario (from poster above yours): they give the few misguided complainers a free contract termination, and what happens? EVERY SINGLE 3G CUSTOMER still on a contract will want said free exit too. AT&T will lose $200 for every customer who chooses this.
OT:
