Even this list itself shows such an example. It calls out the expression "calling a spade a spade" as problematic, and the explanation given is "Although the term has its origins in Greek literature, the subsequent negative connotations with the word "spade" means that the phrase should be used with caution or not at all.". So they are inventing some redefinition of the phrase that could be problematic in order to jettison it.

Note: as a non-native speaker, I have no idea what is problematic about the word "spade". I have only ever seen it to mean either a tool for digging or a type of sword, but I will take them at their word that it does have some other meaning.
