What judge approved all of these DOJ supoenas?

1. Magistrate Judge Deborah Robinson

The nondisclosure order was extended three times, each time for a year, Apple said. When it was not extended for a fourth time, Apple said it informed the affected customers on May 5, 2021.

"In this case, the subpoena, which was issued by a federal grand jury and included a nondisclosure order signed by a federal magistrate judge, provided no information on the nature of the investigation and it would have been virtually impossible for Apple to understand the intent of the desired information without digging through users' accounts," Apple said in the statement. "Consistent with the request, Apple limited the information it provided to account subscriber information and did not provide any content such as emails or pictures."

The subpoena was signed by prosecutor Jocelyn Valentine and authorized by Magistrate Judge Deborah Robinson in DC federal court, the source familiar with the request said.
