Another example: they ignored IndexedDB for a couple years after every other major browser implemented it. Then they finally got around to releasing a version of Safari with IndexedDB support... and it's just hilariously broken in so many ways http://www.raymondcamden.com/2014/09/25/IndexedDB-on-iOS-8-B...

I literally cannot fathom how such a horribly buggy release could be made in good faith. It's like nobody even tried to test it or use it before releasing it.

So, conspiracy theory time: They're doing all this to cripple web apps and force people to write native apps. This conspiracy theory also fits in nicely with how they won't let you run other web browsers on iOS, which would make the deficiencies of Safari somewhat less problematic.
