Seems to be a lot of hate for this policy, but the goal is simply universal interoperability, which is laudible. Otherwise we might as well go back to the days of IE6, since apparently there is absolutely no problem with Embrace-Extend-Extinguish, as long as we can have emojis on our Macbooks.

Edit: I should add that, since it doesn't appear to be a true interop issue, it may not be a sound decision here. I'm defending the rationale for the policy, not this particular application of it.
