>One of 6tag's features is supposedly 'hide sponsored posts (beta)' which really highlights the urgency as to why Instagram would need to build their own client.
It would take all of 10 minutes for Instagram to shut down 6tag if they decided to kill it because of the ad hiding feature.All they would have to do is call Microsoft and tell them to shut it down, an OFFICIAL Instagram client has been one of the "must haves" for the platform and is often cited when tech pundits complain about the anemic Windows Phone app ecosystem. If Microsoft caved on their own WP Youtube app that hid ads they wouldn't hesitate to nuke an indie dev's app if it threatened the adoption of WP with a high profile service provider like Instagram.
