I'm sure it really bugs you that Webster says:
im·pact
noun: impact; plural noun: impacts
/ˈimˌpakt/
1. the action of one object coming forcibly into contact with another.
"there was the sound of a third impact"
synonyms: collision, crash, smash, clash, bump, bang, knock, jolt, thump, whack, thwack, slam, smack; contact
"car parts were spread by the impact over a wide region"
2. the effect or influence of one person, thing, or action, on another.
"our regional measures have had a significant impact on unemployment"
synonyms: effect, influence, impression, footprint; More
That's true. Of course that doesn't make it right:
Definition of literally1 : in a literal sense or manner: such as
a : in a way that uses the ordinary or primary meaning of a term or expression
He took the remark literally.
a word that can be used both literally and figuratively
b —used to emphasize the truth and accuracy of a statement or description
The party was attended by literally hundreds of people.
c : with exact equivalence : with the meaning of each individual word given exactly
The term "Mardi Gras" literally means "Fat Tuesday" in French.
d : in a completely accurate way
a story that is basically true even if not literally true
2 : in effect : VIRTUALLY —used in an exaggerated way to emphasize a statement or description that is not literally true or possible
will literally turn the world upside down to combat cruelty or injustice— Norman Cousins
Just because Webster says it's OK doesn't mean I can't bitch about it
