Apple said the removed The OG App was found to be accessing the Instagram service in an unauthorized manner, hence violating the terms of service, which it said the latter owned Meta. According to the company, it referenced section 5.2.2 of its App Store review guidelines, which states that if an app is displaying content from a third party service, it should do it according to the service's terms of use.
The headline to the story has been changed to include Apple inputs.

Last week, a startup called Un1feed launched an Instagram client called The OG App, which promised an ad-free and suggestion-free home feed along with features like creating custom feeds like Twitter lists. The app raked up almost 10,000 downloads in a few days, but Apple removed the app from the App Store for violating its rules earlier this week.

Un1feed separately stated that Meta had disabled personal Instagram and Facebook accounts of all its team members.
Meta declined to comment on whether it asked Apple to remove the app from its App Store, however it mentioned that the app was violating its policies.

"This app violates our policies and we're taking all appropriate enforcement actions,.

In response to the pulling of The OG App out of App Store, Un1feed called the "collusion" of Apple with Facebook.

"Everyone knows Instagram sucks, and we made it better and got a lot of love from users. But Facebook hates its own users so much, it's willing to crush an alternative that gives them a clean, ad-free Instagram. Apple is colluding with Facebook to bully two teenagers who made Instagram better," the startup said in a statement to TechCrunch. We have asked Apple for a comment and will update the story if we hear back.

The app is still available in the Google Play Store, and founders of the new messenger note that Android is "the obvious choice for users who want privacy, freedom, and optionality." The developers added that they also continue to work on listing the app on the App Store again, but this is not likely to take place in this format and after such words.

Even after launching, there were a few users voicing concerns on login methods, wherein some got locked out from access to their account or prompted to login from a different location. The app, OG App explained it has reverse engineered the Android API for Instagram in order to get some of the things working while at the same time working on a new login experience that solves a lot of problems.

The OG APP reported last night that several apps on the App Store closely imitate the Instagram experience. Of course, some desktop apps are likely to be simply wrappers around Instagram for the web. For now, ad-free Instagram client seekers can hold on tight for iPhone users.
