People for some reason believe in FTL travel through propulsion and I am perplexed. Where did this come from?

I have been arguing about basic physics principles, and I am unsure why.

Even a simple google search say's "The speed of light is considered the ultimate speed limit because according to Einstein's theory of relativity, as an object with mass approaches the speed of light, its mass increases infinitely, requiring an infinite amount of energy to accelerate it further, making it physically impossible to reach or exceed that speed; only massless particles like photons can travel at the speed of light."

So why do people consistently claim that characters like Omni-man are Faster than Light ?

Are they smarter than Einstein? Where did this belief come from?
