I don't think this means what you think it means...
Every single broker like Robinhood sells order flow to electronic trading firms. This flow is then executed faster due to improved market access. All of that to say that you're probably getting better execution because Robinhood wasn't stupid enough to try to go through some crappy broker or build their own order entry system.
Also, the order data can not be mapped back to you. That simply isn't how the stock market works at all. Every single other broker (Schwab, Merril Lynch, etc) does this.

You might work in IT for a market making electronic trading firm (it's not big, I looked them up). I'm a securities regulation attorney. I've worked for banks, hedge funds, and RIAs. This is so far away from best execution that any attempt to argue that this is to the consumer's benefit shows you fundamentally do not understand the fiduciary duties that brokers are supposed to owe to their clients. You're parroting the party line without fully understanding how the system works (and why should you? you're just a distributed systems engineer) yet you have the audacity to tell me in another comment that I've "read Flash Boys" without doing any research and don't understand how the stock market works.
