Paranoid hardware [PART XVII]

Any desktops/laptops/motherboards/SoCs that do not require closed-source firmware blobs out there?

I'm not quite an rms-level nutjob, but I am privacy-conscious and it's frustrating having to explain my computing habits and preferences to people. I don't want to preach and I don't want to seem weird, but people pry and probe. When people ask why ``my Windows'' doesn't have Microsoft Word or why I don't have a Facebook, I feel as though I'm massively responsible. Like when you make someone watch a film and they hate it, you feel awkward about it even though you didn't make the film.

I doubt most of my fellow tinfoil hat-wearing OpenBSD users have friends, but for those of you do, how do you deal with all of this?
