The premise was these guys know your order and buy ahead of you and fill your order in milliseconds shaving a penny or two on your trade. They say everyone in the market is getting screwed by this. They seem to be pushing a new trading platform IEX http://www.iextrading.com/.
I don’t think it is that big of a deal. As my dad used to say “it’s a lotta do about nuthin”. I found the Elon Musk interview a lot more interesting.
