When you think about it, Vibranium in the MCU copied Transformium because it just became the nanotechnology effects that Transformium was criticized for.
Vibranium and Transformium are the same in terms of naming.
Vibranium is a metal that absorbs Vibration.
Transformium is a metal that Transforms into anything.
But only Transformium gets made fun of because nobody knows how Vibranium works and just thinks it's "hard metal"
