Some help:

>is that HFT market makers will give you a price break to route your dumb order to them

You claim a price break on a private exchange. How can they (HFT market makers) deliver a better price than the public exchange? Presumably they cannot have bought it on the public market at the better price, so some party must absorb the loss on the price break.

My question can now be translated to:

Who absorbs the loss from the price break?

When the going gets tough, the questions are dumb? This is the hallmark of lobbyist talk.
