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.
Stallman is often batshit insane, but when it comes to tech he knows what he’s saying.
I would trust a doctor when he says about something about my stomach, I wouldn’t trust them about astrophysics.
I would trust Stallman about how computers can be misused and mistreated, same as Cory Doctorow. I wouldn’t trust both about a small part of history, unless it was obvious or very well cited.
