You have been given the answer repeatedly. Unless the runner commits some act to interfere with the thrown ball such as slapping at it, purposely changing course to be hit by it etc, being hit by the throw is nothing. Running the bases is not an act of interference
You start calling that and you are going to start a beanball session by the defense to get easy outs. It has never been interpreted in any way that a runner hit by a thrown ball is interference unless they commit some act to interfere with the throw.
