don't forget c) it's revenue, and if the thieves use it to pass their bills for calling the most expensive countries on earth onto random passers-by, its not the telco's problem, is it? They're using "Industry standard" security. This is like the (AT&T?) voice mail frauds that were costing people thousands of dollars for choosing poor passwords for their voice mail. Until it hits a certain level, its just revenue enhancement through poor security.
