To be fair and technically correct, the BIOS itself was not backdoored.
The BIOS itself was fine, but it contained insecure Windows-software which it requested/instructed Windows to install.
Install any other OS (like Linux) and there would be no backdoor at all.
To be clear I’m not trying to defend Lenovo’s actions here, I’m just trying to be clear about what this incident was actually about. The simplistic description is IMO a bit too simplistic in this case.
