It's actually industry standard for the publishing platform to take ~30% as the article says. XBLA, Steam, and PSN all do this as well.

It may seem like a lot, but those users wouldn't be available to you without the platform supporting you.

I think the 30% concern is largely from people who see this growing into a paypal sort of service. 30% to sell virtual cow-feed is standard. 30% to sell a book or some jeans is not.

Whether Facebook intends to go that way or not, people seem to be assuming it will.
