Laptops, desktops, smartphones or tablets are closed source hardware with closed source firmware in general. There are products marketed as if they're open source devices which are in fact closed source hardware with almost entirely closed source firmware. The software on top being open source is frequently misrepresented as the device itself being open source, which isn't the case. Not shipping important firmware updates in the OS provides assurance of insecurity while not changing the fact that the hardware and firmware is closed source. It has to do with a loophole defined in a certain ideology around software, not open hardware or privacy/security.
