To a large extent, the two go hand-in-hand. A closed-source platform may give you a lot of freedom to customize things, but what it doesn't give you, you can't have. On an open platform, you can do anything. It's the difference between "most of the doors are unlocked here" vs "if you want a new door, here's a blueprint and a chainsaw."
