Josh Constine, TechCrunch:
Going forward, Instagram’s platform will only permit photo editing apps and ones like Tinder that let you pull in your own Instagrams (but not your feed), brand and ad management apps, and tools for media and broadcasters. Existing apps will need to comply by June 1st, 2016, and the policies and reviews will go into effect for new apps starting December 3rd, 2015.
I’m surprised they ever allowed this access in the first place. Nobody I know uses a third-party Instagram reader, even on an iPad. I bet that Twitter will watch this move carefully, though; I’m sure there are internal discussions regarding the degree to which third-party apps work with their platform.
