Instagram to third-party developers: drop dead

On June 1, Instagram severely restricted what any third-party Instagram application can do. Not only can third-party apps no longer provide the features Instagram’s API supports but Instagram itself doesn’t offer; they can’t even compete with the restricted feature set Instagram natively provides.

The old Twitter gambit—learn from third-party apps; change your own offerings to match theirs; then change your API—looks positively user- and business-friendly by comparison.

Now, I have no problem with Instagram offering a limited feature set. Most great apps reach mass appeal precisely by focusing on a restricted feature set, designed for one or two use cases. And clearly Instagram knows how to reach mass appeal.
