Every exchange gives "good standing market participants" aka HFT market makers first dibs on orders. If a gallon of milk goes on sale and I'm waiting in line with a market maker I will never make the sale, it'll go the the HFT firm every time.
Care to link to a major equity exchange's product page and/or sec declaration that details exactly how this works (ie, criteria for getting "first dibs", what that actually means etc)?
Or are you talking about exchange hosting, where you get lower latency if you pay more to colocate?
HFTs provide liquidity, which by definition is providing what people want to buy/sell, when they want to trade it and it the desired quantity.

This is not what HFTs do. They can't see your "hand reaching", they see your quote hit the book at the same time as everyone else. It's not magic.
They're literally the market makers. Your complaint appears to be that they're good at reacting to new information, i.e. being good market makers.
