Apple and Google’s infamous ‘app tax’ could be under threat App Store

New legislation has been passed in the US state of Arizona that could have significant implications for the way Apple and Google are able to generate income from their respective app stores.

The amendment to the state’s HB2005 , which passed by a margin of two votes (31-29), prevents the two firms from demanding Arizona-based developers use a single payment system exclusively, which in turn poses a threat to their ability to take commissions on app sales and in-app micropayments.
