The reason you're getting pushback on using the term front-running to describe this is that it is a blatant misuse of words for the purpose of painting a behavior as bad without needing to say why. You've taken a legal term that describes a crime and extended its definition to something that is not a crime to make that non-crime look bad. There might be some good ideas in there, but relying on this deceptive rhetorical technique implies otherwise. If you have something worthwhile to say, why the deception?
