From the article:

Here are the things Musk has installed his IT Renfields at:

• The Centers for Medicare & Medicaid Services
• The Consumer Financial Protection Bureau
• The Department of Education
• The Department of Energy
• The Environmental Protection Agency
• The General Services Administration
• The Department of Labor
• The National Oceanic and Atmospheric Administration
• The Office of Personnel Management
• The Small Business Administration,
• The Treasury.

We all learned in 2022, with the weaponization of SWIFT, that technical systems are a source of power. By controlling the infrastructure, Musk controls the nation. The two most obviously significant agencies on that list are the Treasury, which controls the money, and the Department of Energy, which controls the nuclear secrets. Less obviously significant but equally troubling is the General Services Administration, which is effectively the infrastructure of the government itself.
