Is that true? As I understood it, the original request was for pen/trap on Snowden alone; when that was refused and Levison threatened with contempt, he relented, only to be rebuked by DOJ with a new demand for blanket surveillance.
But as I understand it, Levison could have complied with the earlier demand for surveillance narrowly targeting Snowden.
Your understanding is not accurate from my read of the court docs. They wanted their black box (you know the ones), called a pen/trap device in the documents, to be installed on the network. It won't work without the SSL keys, so they wanted those. He offered to modify his software to intercept a single user's email, but they said no.
