Kanye West went on an epic Twitter rant about his daughter making in-app purchases on an iPad

Kanye West, who normally makes headlines with his fashion endeavors and music, recently took to Twitter to express his outrage about an unlikely subject: in-app purchases.

West's daughter North had apparently racked up a decent number of purchases in "kids games" on the family's iPad, and the "Yeezus" rapper and future presidential candidate wasn't pleased.

West touched on a nerve that Apple has already been forced to address in court.

In January of 2014, Apple agreed to a $32.5 million settlement with the Federal Trade Commission over a lawsuit from parents who said the company of made it too easy for their kids to make in-app purchases in games downloaded from the App Store.
