Billionaire IAC chairman Barry Diller has mixed feelings about Elon Musk's Twitter acquisition.
On CNBC's Squawk Box, Diller said Musk "bought a toy, and how long he will use it, like toys, we don't really know."
"You've got this extraordinarily wealthy person, and he bought a toy," Diller said.
"He bought a toy, and how long he will use it, like toys, we don't really know, but he's not going to walk away, I don't think."
By headcount, however, Twitter is already much smaller in the days since Musk bought it.
