In my world, where I try to look at things in the obverse to gain perspective, this might actually be a strong move for Instagram. Akin to new Coke. The people that really love Instagram will weigh in, not shut down. If the platform is worth saving, and I suspect it is, the masses will help with the solution. New Coke was one of the best things to happen to old Coke and this move by Facebook (recent purchaser of Instagram) will likely end up being the same – though I’m not sure Fothcbook is this devious. More likely they are stepping on their you knows. Hee hee.
Monetization is not the enemy. Lack of outside perspective is. In 6-9 months, Instagram will have a new monetization plan in place, whereby some of the photos on the platform will be available for sale, others not, and all will be well. This is the word of the future. Peace!
