One of the libraries we use is licensed under the WTFPL. Legal is saying we can’t use it because it has f*ck in the verbiage. Any recommendations?

One of the libraries we use is licensed under WTFPL. Our legal department is saying we need to rip it out because the license is not valid because it contains the f-bomb.

Is there any way I can explain to them that, it literally means… do whatever the fuck I (we) want?
