  Well, it's a difference in capacitance. It really does not cost much for them to be made as 2.1 amp rather than 1. So you could make the argument that charging more for a better product when the costs to make it are the same is a scam of sorts.
context: What’s the scam exactly? They sell the best charger for the phone. If a 3rd party cable works way worse but it’s much cheaper, that’s not exactly a scam. >
  
  It's also likely the block that the 3rd party companies are using. Apple & Samsung use higher Amp blocks to charge faster. Which comes at a premium, if you want the absolute fastest charge for your phone, you have to pay for it, and then take care of your shit! Don't lose it, don't bend the cord (especially near the ends) in awkward positions if it's semi-rigid, etc..
