The app store model is a more immediate threat to internet freedom than breaches of net neutrality. That’s the opinion of Wikipedia chief Jimmy Wales.
According to Wales — who was quick to stress he was speaking in a purely personal capacity — set-ups such as the iTunes App Store can act as a “chokepoint that is very dangerous.” He said such it was time to ask if the model was “a threat to a diverse and open ecosystem” and made the argument that “we own [a] device, and we should control it.”
