Yeah, the headline certainly follows the clickbait tropes. But in this case, it appears to be legit - experts actually don't know and the vendors keep it a closely guarded secret.
It kills me that every researcher the writer contacted has never actually seen the plant or bothered to go look for it, including the guy that studied agave!
It's not a question of the competency of academics.
> So why is there still doubt about the identity of this snack? “Which species of agave is it—Sisalana or Americana or any other?” Dr. Shimpale says. “We can’t conclude until the vendors show the plant to us. They keep this as a business secret to create curiosity around it.”
The vendors won't give them access to the source, so the academics can't practice their botany.
