??? How is it wrong?
Just because some/many/all request something, does not mean it is/can/should be implemented.
Of course it does. That's what feedback is all about.
Clearly the majority of users does not send feedback. So we cannot speak about a majority in apple users. But. There are other ways to measure this. And Im gonna assume now, not blindly, based on the hundreds of threads, articles, and forums that pop up when you search "move photos from camera roll" that this feature has been requested multiple times and along a very extensive frame of time. Apple has ignored these repeated feedbacks, systematically along the years.
So much has been the claim for this feature that apps have been created to achieve this. Do you really think that developers would invest their time and resources into creating an app that would not be profitable, or would no be used by many? And its not even one guy that has seen this trend, many many developers have seen it, and so they are many apps out there promising to do this.
The flaw in the design is then clear. Its not subject to opinions. Some people suffer it more than others. Some really dont care about organization, some dont use images that much. But its there.
The real question here is, is it profitable? How expensive it is? What changes need to be made in IOS to allow this?
If many request something (with good reason), it should be implemented. It definitely can be. Will it? Not always, but it should.
