Steve Kirsch is a tech entrepreneur who made hundreds of millions of dollars after founding an early search engine and helping invent the optical computer mouse.

Recently, he stood before a gathering of more than 250 lawyers in Atlanta while wearing a custom black T-shirt designed like a dictionary entry for the phrase "misinformation superspreader."

"Our definition is it's someone who's basically pointing out the truth and it just happens to disagree with the mainstream narrative we're known as misinformation spreaders, because what they're trying to do is they're trying to control the narrative," Kirsch told NPR.
