CNNMoney readers disagreed about whether this was a good move.
jones19876: "I don't see the point, and certainly not the value in this; Instagram may bring 30m users along, but Facebook already has them in their grasp, it's like buying an extra copy of a DVD you already own."
Jason Crow: "Sometimes the investment is in keeping users. Instagram was quickly becoming a leader in an area that Facebook currently dominates, which is the sharing of photos. I think Facebook is being proactive here."
This reader said the development was inevitable.
honda333: "Well, I can tell you that everyone I know uses it daily and a lot of people like it. ... I don't like it, but every picture I see on Facebook now is Instagram. I think it's a smart business move on Facebook's part. If you can't beat 'em, buy 'em."
But many users seemed to be upset by the idea. We heard from many people on Instagram via our CNN iReport account, where several expressed outrage.
"I got on Instagram to get away from Facebook, and now they've even ruined this, too," commented user soufflesoiree.
A few were indifferent.
"As long as they don't mess it up, it's fine, I guess ..." said nbbx.
We also received several iReports from users who posted images expressing their views.
Aline Alencar of Rio de Janeiro, Brazil, writes, "I think it's very bad for all users. In Instagram, we have a small social media (community) to conform to. A lot of users will stop using Instagram."
Reno Moeller, an investment manager and photographer from Discovery Bay, California, talked about some of the business consequences.
"The pros are that apps like Tadaa are getting more users since the announcement. The cons are that Instagram was an escape from Facebook, a different community, a creative one, and now that's gone. ... A big reason artists or creatives don't use Facebook anymore is because we don't trust them. We don't trust their policies or like what Facebook stands for anymore. If I wanted to post my work to Facebook I would. Facebook doesn't care about the pictures or the art. They just want the users. They want the data."
But the biggest question might be ...
This reader wrote that they felt a deep sense of disappointment.
Matthias: "This shows one more time that all the 'social' Internet is going into a wrong direction. We all took pictures and Instagram sells what we have created, making a hell of [a lot of] money. We need communication between people where everybody owns what he created and not a third company. I feel like somebody has stolen something from me. I actually had the same feeling a few months ago when runkeeper changed the graphs in his fitness reports and all the data I've collected over years was useless for me from one day to another. I am starting to get tired of this Internet, which is so far from the freedom it was supposed to bring to us at the beginning. It's all about making a few people incredibly rich using millions of users. … We all know that but I think it's time to make a change."
Another person said there are various possibilities.
alexDW: "Takeovers are different. Skype has been owned by Microsoft for a while and afaik nothing has happened with it at all. When Siri app was bought by Apple that meant its Android app development was ended immediately. Even its Apple app disappeared and Siri became a built-in feature of one iPhone model. We will see which way Instagram goes."
And then, for the Star Trek fans, there is this comment.
