Seeking concise expression or word for "Taking ownership of an existing term used by an adversary, then using it against them."

As example:
"“While we have already tried to build a new and viable society around concepts such as democracy, sustainability, sustainable development and resilience, all these terms have been corrupted by forces determined to incorporate and embed them into the Anthropocene where they become ‘business as usual’.” in Exiting The Anthropocene and Entering The Symbiocene.

I seek a word or shorter phrase to express the words in bold font.

Also encountered in a French language conversation when the term – neo-colonialism – was taken and used in a manner contrary to it’s original intention.

A word or short expression for using the enemy’s (verbal) weapons against them.
