Instagram has backed away from controversial changes it planned to make to its terms of service. Co-founder Kevin Systrom has used the company blog to announce that the most sensitive phrase in the terms will be revised. The update would have given Instagram the right to sell user’s images to third parties without compensating them. Systrom says this was never the company’s intention. Instead, he says, wording will be developed to allow it to associate information such as users’ profile images with commercial postings (as Instagram’s owners, Facebook, do).
