I agree that a co-ordinated effort could work, however, to cause Apple the maximum amount of brand/financial damage, it should be timed to the release of the new iPhones. If Spotify, Youtube and Netflix all pulled their apps a day after the release of the next phone, Apple would be in serious trouble that year. It would effectively permanently devalue their phones and by proxy Apple, because consumers wouldn't be able to trust that that it wouldn't happen again. It would certainly spook investors.
