Facebook won't launch its news subscription service on iOS due to Apple's 30 percent tax

While discussions are still underway, the negotiation is at an impasse, so Facebook has decided to go ahead with the launch of the news subscription service, but only on Android devices.
Furthermore, the “freemium” version of the news subscription service will allow publishers to put paywalls around individual articles.
As mentioned earlier, Facebook will not take any money from the publishers, however, Apple's absolutely must have a piece of the pie, and that's a problem.
