If you want to define front-running that way, then I agree HFTs don't front-run. But they do step in between buyers and sellers. If you want to call that something else, shrug.

Stepping in between buyers and sellers is called market making. They smooth supply and demand across time.

Also I don't define front running that way, FINRA does.
