On one of the Debug[1] podcasts (I can&#x27;t remember which one now), Don Melton[2] claims the decision to not allow other web rendering engines or Javascript implementations is because they don&#x27;t know how to allow those and keep iOS secure, and that is the reason behind a lot of limitations enforced in iOS.<p>Apple is certainly more closed than Microsoft ever was.  The difference in perception is likely because Apple has never had a monopoly.  There are more Android phones than iOS.<p>[1] <a href="http:&#x2F;&#x2F;www.imore.com&#x2F;debug" rel="nofollow">http:&#x2F;&#x2F;www.imore.com&#x2F;debug</a>
