Now, take a deep breath, go and read the old license, read the new one, and realize it just got MORE stringet for Instagram.
In the midst of all the sensationalist hype by less reputable sites like CNet and other cheap shot, hit gathering ones, The Verge actually took the time to write a semi-decent one: http://www.theverge.com/2012/12/18/3780158/instagrams-new-terms-of-service-what-they-really-mean Several more legalese and copyright focused websites concur. What is even funnier in all this, is that people are jumping ship to another app or two, or back to flickr, without realising that the apparently more restrictive, but in reality just vague, terms of those ACTAULLY do screw you up. In example: With the change of license Instagram has basically waived the right to derivative work coming from your pictures, the alternatives people want to jump ship to haven't. This is exactly the same crap of the name of the brother of the shooter going viral a few days ago, or when people were pasting the inanely stupid posts on facebooks about not giving permission. Ignorant people jump to conclusions, they write an article about it, and because it's on the internet it must be true. I detest facebook as much as anybody else with half a neuron has, especially for being circumstantially forced by peers to use it for certain parts of my social life to function, but in this case it's just people jumping the gun. As you were.
