Why did a senior engineer from the GSA resign?

A senior engineer from the General Services Administration (GSA) resigned after attempting to block one of Elon Musk's associates from accessing notify.gov, a secure government system. The engineer was concerned about privacy issues related to this sensitive platform, which connects federal agencies directly to citizens' personal cell phone numbers and information. Notify.gov contains highly sensitive data linking citizens' personal information with their involvement across multiple government agencies. The engineer took a stand against the Trump administration's effort to grant access to Musk's associate, demonstrating serious concerns about protecting Americans' personal information from potential privacy breaches.
