I do know you can download Ubuntu’s theming/color scheme on most Distros, including Debian. And if you like the logo, you can tell Fastfetch to show any logo/image, and branding is often a simple check on Plymouth/related configs.
Debian is what I use when I need Ubuntu-tier support.
Like the CIA blacksites, Gitmo, the Fed vans that pulled and kidnapped protestors during the BLM protests? Or the fact that police can get away with murder in broad daylight and people who fight it are labeled terrorists who hate the country?
