Seems like this book is causing quite the ruckus with certain brokerages: http://pressroom.aboutschwab.com/press-release/corporate-and...

Yet they are more than happy to sell their order flow to market makers who use HFT. (To allow them to trade against it before going to the exchange - as is customary - nothing wrong with that) http://www.schwab.com/public/schwab/nn/legal_compliance/impo...

Seems like they are jumping on the populist bandwagon by claiming "HFT bad!" but I think what they mean is "HFT bad - unless it's from one of the firms we sold our order flow to!"
