Yeah, facebook bought them for a million or something a few years back and now has decided that if you have an instagram account they can sell your photos to advertisers and sponsors and such for a profit. It's getting a lot of backlash on the web. Basically like anytime facebook changes their agreements and such. You can opt out by canceling your instagram account and deleting all your photos by January 16, but after that if you still have photos and your account it's all theirs.
