Apple underestimated the time required to bring the App Store into compliance, sources told ZDNet. The publication speculates that the issue could be due in part to the need to make additional changes to iTunes on the desktop, with the app's 13-year-old codebase presenting a challenge.
As part of the settlement, reached with the FTC in January, Apple agreed to modify the in-app purchase process to ensure each purchase was expressly authorized by the consumer. That likely means abolishing the current 15-minute window in which users do not need to re-enter their password after making an initial purchase, a period in which children or other unwitting users have accidentally racked up huge bills.
The changes may also be delaying the release of iOS 7.1, ZDNet surmises. Apple is thought to want to roll the FTC-mandated alterations in to iOS's next point release, which many Apple watchers expect to drop "any day now."
Apple agreed to both the App Store adjustments and a refund program in the amount of $32.5 million in exchange for the dismissal of an FTC-backed lawsuit. The company did not appear to be happy with the idea of a settlement, with CEO Tim Cook saying it "smacked of double jeopardy" since Apple had already agreed to refunds for affected consumers and altered the App Store's behavior, but Cook chose to accept the settlement to avoid a "long and distracting legal fight" with the regulator.
