The linked article says removing the name would require returning the money per the terms of the contract and "the hospital agreed in 2015 when it accepted the $75 million that it would keep the Zuckerberg name for at least 50 years."

Another article [0] says "[...] Zuckerberg SF General Hospital, a name the Zuckerberg-Chans bought themselves in 2015 for $75 million."
