Jeff Bercovici on Apple’s opt-in policy for sharing personal subscriber information to publishers:
Initially, publishers were worried, reasonably enough, that users
would overwhelmingly say no. But they don’t. In fact, about 50
percent opt in.
Mark Edmiston, founder of the tablet magazine studio Nomad
Editions, first heard that figure from other publishers, so he ran
it by Eddy Cue, Apple’s vice president of internet services. Cue
confirmed it. “So, all the sudden, what was an insurmountable
obstacle no longer is,” says Edmiston.
