The nuance here, based on the EO, is rank file and employees of these agencies must now rely on the sole interpretation of the law by either the president or the AG instead of themselves. These _were_ independent agencies who handled their own interpretation of the law.

If you combine this EO with the Supreme Court immunity decision, there may very well be a situation where a rank and file employee acts illegally based on the president's interpretation of the law. This would create a situation where there is a legal challenge about whether a member of the executive branch should be granted the same immunity privileges as the president since they are an extension of the president. You can imagine where things will head if we end up on the wrong side of this decision.
