Yeh, the difference between being high value (twitter) and an actual high value (government) target are entirely different.

Exactly. Tesla or Twitter might be on a country's radar for juicy IP theft reasons, but that's a speck of dust in comparison to a network full of classified government secrets. A country doesn't burn multiple zero-days and backdoor supply chains to find out the contents of the next Tesla firmware update. They sure as hell do when it gives them access to military information and civil infrastructure of a world power.

I wonder if DOGE have reputable hardware, or if they cheapest out on servers.

I doubt it. If the way Elon talks about software is indicative of his understanding of hardware or cybersecurity, he has absolutely no idea what the fuck he's actually doing. Knowing that, it's probably an off the shelf commercial rack-mount with IME enabled and the management port plugged into the same switch as the regular network interface.
