Tin Can and Walled Gardens

Did some looking into the "tin can" app, and I was disappointed to learn that it is only available on android devices! According to Casey Johnston, "The app is available only to Android phones for now and may soon make its way to Windows Phone, but Katakowski suspects that Apple will never allow Tin Can into the famous walled App Store garden." Here is her article: http://arstechnica.com/gadgets/2013/11/tin-can-app-relays-messages-to-phones-without-internet-cell-reception/

I was interested in this comment. Especially the phrase "Walled Garden", so I searched for more about walled gardens. Turns out that it is a phrase from the early days of internet. It refers to a closed platform. It was the approach that internet providers used in the first years of internet. Today, it is the philosophy that Apple uses.
