No. They are blocking applications which allow you to make purchases without using Apples in app purchasing system. See the difference ?

...and using the Dropbox SDK is apparently violating that

THIS version does. And a NEW version doesn't.

There is no specific probelem with Dropbox.

But... there... was? Not too long ago? And it might require action by users of the Dropbox SDK?

I get notifications of security updates for apache. Guess I shouldn't though, because by the time I get any it's no longer a problem with apache. Maybe I should tell my security auditor that?

The new version is hobbled and won't even let you make an account. It is nothing more than a workaround for apple's stupidity.

The difference is that the title will go over 80 characters and won't make it to HN, this is not Reddit.

I don't get the complaints about the HN title, it's reasonably accurate given the space limitations and the forum further clarifies things. Not everything can fit in the title.

Also, I see a distinct lack of suggestions of a better title, just complaints that it's link bait.

A much more accurate title like

    Apple Rejects Some Apps Using (Old) Dropbox API

is only 47 characters.
