Similarly, Cryogenics is the science of keeping things really cold. And of course Cryonics is a form of that. But saying "Cryogenics" when you really mean exactly Cryonics is an incredibly harmful practice which actual Cryonicists generally avoid. Most people who work in Cryogenics have nothing to do with Cryonics, and this kind of confusion in popular culture has apparently engendered animosity towards Cryonics among Cryogenics specialists.

I wouldn't so much call that "inflationary". I'd usually call that a typographical error! ie. The speaker is usually intending to use the label of the corpsicle specific practice and just said it wrong.
