In the preface to the changes, Instagram is quick to point out two important details — users still choose who can see their Instagram photos, and they still get to choose whether they post photos on Facebook
From the new policy:
“We may share User Content and your information (including but not limited to, information from cookies, log files, device identifiers, location data, and usage data) with businesses that are legally part of the same group of companies that Instagram is part of, or that become part of that group (“Affiliates”). Affiliates may use this information to help provide, understand, and improve the Service (including by providing analytics) and Affiliates’ own services (including by providing you with better and more relevant experiences).
