> Do any other companies do the same?

Important relevant note:

Some companies offer "DOS" or "FreeDOS" computers. This is notably common in poorer countries.

These commonly do not really run DOS. They run a very old version of FreeDOS in a VM under Linux. HP uses Debian.

1. When you look for Linux machines, look in other countries than your own.

2. Include machines described as DOS machines. They are really Linux machines and will run Linux fine because they in fact ship with it.
