Yes, anything can be weaponized. The question isn't if something can be used as a weapon, it is if that thing also has good and proper uses beside as a weapon.

Antidisinformation is just a different word for counterpropaganda which is just propaganda used by us instead of them. Even the term 'propaganda' has been more positive 80 years ago, it just underwent the usual euphemism cycle, so now we are at '(counter)disinformation', 'fake news' and 'fact checking'. Which all is just a nice word play for the thing it all is: information warfare. (of course calling it 'warfare' is also propaganda)
