Despite Elon not having been appointed for anything nor have any congress endorsement, DODGE is acting as some short of paramilitary force forcefully taking over the systems of several administrations - including the FBI - and illegally gathering personal information from thousands of government employees.
Since the people who would normally prosecute this are basically the FBI and other agencies that are being raided, there is no real option for asking for justice or prosecuting.
I am sure some in the US are absolutely OK with this, but for some it may be starting to look like a dictatorship in the building. All the institutions under threat, the justice system no longer independent from the executive and a congress that is unable to control the wildest illegal actions of the executive.
Be careful of what you wish for, you may get it.
Even if Elon Musk has not been appointed by anyone or has not even directly elected by the people of the United States to be part of the administration of that country, it is clear those who voted for Trump did not have any problem with the endorsement and the involvement of Musk into American politics, actually, there were many people who explicitly voted for Trump because of the endorsement and support he started to get from Elon, they are perfectly comfortable with the country stepping into oligarchy territory, which is kind of scary.
One also must wonder why Musk would like to have access to such information... He and Trump could be planning to execute a nationwide purge of public employees, as explained in project 2025, in which those who do not politically align with Trump vision for the country would likely be kicked out their position and replaced by yes people.
