Unfortunately you can't even find a Linux computer in shops anywhere, which could be the reason few people use it. It's actually harder to find malware there.

Funnily, you can find various somewhat-Linux devices in stores mostly, except they're called 'Chromebooks'. This is the same device series that uses Coreboot as a boot loader and usually had an internal screw to remove to disable firmware write protections and fully unlock the device, as well as other visually and auditory (they make a large beep on boot) tamper-evident 'developer unlock' modes. Nowadays instead of the 'unlock screw', there's a mandatory security chip that can be unlocked into a less visibly tamper-evident mode in which it is disabled via a special USB-C cable for sale on the open market with a reference schematic available as well, which is a much more fun solution to assert physical access.

Many older models also would run mainline Linux fine, and the default Chrome OS install usually has a container and a Wayland to Chrome adapter behind a toggle.

I don’t think it’s relevant for the general public.
