Wicked problems

Wicked problems. I’d never thought much about this term until at a recent Te Pūnaha Matatini hui one of the investigators said they didn’t use it as it’s offensive in some of the communities they work in and with. Huh. OK. That’s a curveball. Is this another version of the brief ‘political correctness gone mad’ flashpoint ‘can’t say brainstorming’ in case it upsets … someone (allegedly people with epilepsy, but this has since been carefully deconstructed by the Epilepsy Society), or is there something in it? Is it something that just needs clearly disambiguating/contextualising when it's used, or should it be avoided?
