RSS app: How to get approval for App Store?

I submitted a RSS reader app, but it just got rejected from the App Store, with this cited:

8.5: Apps may not use protected third party material such as trademarks, copyrights, patents or violate 3rd party terms of use. Authorization to use such material must be provided upon request

We found that your app contains features that may infringe on rights owned by various news and media outlets.

Specifically, we found that your app provides users with a news feed generated from them.

Please provide documentary evidence of your rights to use this content.

Acceptable documentation includes a copy of your contract with the copyright holder or a detailed authorization letter from the copyright holder to your company. Please make sure the documentation you provide specifies the rights for commercial use as the App Store is considered a commercial environment, even if you choose to offer your app for free.

I'm wondering how all of the other many many RSS reader apps got approved, so that I can figure out what to do to get mine approved too.

My app just generates a feed based on interests you select. And that feed pulls from RSS.

Would greatly appreciate any help at all, thanks!!
