The whole idea of instagram was "instant postcards". The idea that they would help you do make these. Not that they would go creep out shots of your family and sell them for a profit to 3rd parties without consent. Or sell your data to be analyzed and fed into behaviroual profiling for junk mail. If they want to charge for postcards, then nobody would complain in this way.

Instagram is (now) just a clever form of social engineering...not a product.
