Long ago (and probably more recently as well) there was a funny little info-graphic regarding which mobile companies were suing which. Has anyone stumbled upon a similar summary of knowledge regarding who is banned from selling where? I honestly don't know who started this whole thing and I don't want to point fingers but it feels as though someone thought it was a good idea to try and block the sales of some product and opened a whole can of shitstorm.
