App rejected inconsistent reason

Hello guys,

Been an iOS indie dev full time 2009 - 2015. And part time till now.

So I made a simple app to download GIF images from tweets using Twitter API. Tested all works ok and submitted.

2 days ago, got a reply from Apple that my app is not complying section 5.2.3 - App that downloads content from 3rd party, must have permission for those content. Obviously users can download copyrighted GIF from CNN tweets for example... (I am a bit confused because, how about Chrome browsers? It can do the same thing why isn't that a problem?)

So I add a disclaimer requiring user to agree that whatever they download will be only for personal use, and resubmit. Today another rejection -Guideline 4.2 - Design - Minimum Functionality

It is a tool to download GIF, even able to modify the GIF frame rate and speed. I would not add any more features to it, lest it ceased to be a GIF downloader.

Have never encountered such ridiculous rejection before. Any idea how to pass the review for such apps? Or should I just forget it and release on android instead?
