Again the Palantiri were communication and surveillance devices used in times of peace. A warhammer by contrast is weapon whose sole purpose is to create violence. (Perhaps a better counterexample here is Palmer Luckey's company Anduril, named for Aragorn's sword, a "weapon clearly for good".) Yes Sauron hijacked the communication channels, but Sauron also corrupted literally everything he touched--he would have caused the same evil if he was doing morse code on a telegraph.
