Topic: Should I update my CPUs microcode?

I read through the ArchWiki's Security page https://wiki.archlinux.org/index.php/Security
and was led to believe I should update my CPU's microcode to protect against any vulnerabilities.

However, I read on Libreboot that microcode updates for some CPUs
may be a bad thing as they could introduce new security flaws.

What can anyone tell me about this?

If you are using coreboot, libreboot or have intel me neutered, do not do it especially... but in general its a horrible idea. It's like a black box type situation. let's just say that...

Aka, intel bios firmware upgrades are usually very proprietary...

some does it but its before you libreboot it, as zapper said its a horrible idea, knowing that yours have libreboot on it already.
