Is the Intel FSP blob a backdoor? (lemmy.world)

Libreboot supports the Dell 3050 Micro and the Lenovo T480. I was wondering, since it requires the FSP blob, could it be a backdoor? Does anyone know how it works? Compared to the T440p and 9020, those boards are 100% free BIOS, but lack newer microcode updates.

By its limited scope of just initializing the chip, it seems a lot more benign than Intel ME, which would be a jucier target than the FSP. But no independent audit has been completed on it to my knowledge. Purism got started with an attempt to reverse-engineer it (legitimately without the leaked code!), but Intel told them to take it down, which is a bit troubling.

I wonder if anyone got the archive of that article.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
