To build out this metaphor a little more, John Deere makes the tractor (phone OS) which pulls machinery (apps - plow, fertilizer spreader, harvester, etc). This would be John Deere controlling which equipment the tractor may or may not be allowed to pull, only machinery allowed by John Deere who gets a 30% cut for the privilege. This would be a great deal for Johnny D!
