I've been exchanging tweets today with Micah Bowers, the head of Bluefire Productions. He's confirmed that as of this morning that the Bluefire Reader app no longer has
the buy links to partners' websites.
You'll need to open the app to see the difference, but don't worry. You will not have to download an update. The only part of the app that changed was the Get Books tab. This part of the app is based on content pulled from web servers. This let Bluefire change the content without actually having to update the app.
Bluefire Reader is probably the most popular independent reading app on iOS. It supports Epub and PDF, and it comes with 5 ebookstores integrated into the app. (You can't buy ebooks anymore, but you can still download them. ) It also supports library ebooks.
Unfortunately for us, not all of the ebookstores will be able to adapt as quickly as Bluefire. At the very least, Amazon and B&N will need to resubmit their apps, and I'm still not sure what Kobo plan to do.
