Calling all Armenian proverb explainers: All Balls, No Shaft (Musk v. Zuck) - eviltoast

I found this on The Verge, though it originated on Vice. I tried posting a screenshot, but that didn’t work:

“Zuckerberg is clearly the Mullah Omar of this situation,” Shabanian said, referring to the founder of the Taliban and previous ruler of Afghanistan… “You may not like him, but at least you know what you’re getting. And it’s uniform across platforms and districts. Unlike going with Musk, who represents a lawless, profit-driven society. Musk is all balls, no shaft, as the ancient Armenian proverb goes.

Any thoughts on the story behind this proverb?
