Now, tell me which rule you will cite in calling the batter out, not just ejected??

There is no rule, unless you somehow classify intentionally messing with a foul ball (that might become fair) in the same category as throwing a bat in anger.

If there isn't a rule against a batter, coach, runner, intentionally interfering with a batted ball that has a chance to become fair, there should be.
