Instagram had previously announced that it would be revising its policy update plans due to the controversy.
"There was confusion and real concern about what our possible advertising products could look like and how they would work," Systrom wrote in his post Thursday. "Going forward, rather than obtain permission from you to introduce possible advertising products we have not yet developed, we are going to take the time to complete our plans, and then come back to our users and explain how we would like for our advertising business to work."
Here's the language that caused the kerfuffle:
Some or all of the Service may be supported by advertising revenue. To help us deliver interesting paid or sponsored content or promotions, you agree that a business or other entity may pay us to display your username, likeness, photos (along with any associated metadata), and/or actions you take, in connection with paid or sponsored content or promotions, without any compensation to you.
"I want to be really clear: Instagram has no intention of selling your photos, and we never did. We don’t own your photos – you do," Systrom wrote Thursday.
