If a single entity controls the platform for it, a programming language is effectively owned. For all practical purposes, Apple owns the platform for Objective-C. If more apps are developed using a cross-platform standard like HTML5 than a single-platform like iOS, that reduces lock-in, so why would Google or Apple want that? That Google want HTML5 to succeed (despite their own Android platform) is pretty much given. The author, however, is arguing that Apple also wants HTML5 to succeed. Why? To prevent another platform from successfully competing with iOS, so that Apple can continue to offer the best user experience.
