What is the convincing reason that MicroSlop is the trusted party to sign the shim with their (presumably NSA-blessed key)? Why is there no charitable equivalent like a small/mini LetsEncrypt foundation for the PKI aspect of Secure Boot? I also do not see a convincing reason it meaningfully improves security posture.

You can load your own Secure Boot keys and sign your bootloader yourself; as for why the Microsoft ones are preloaded, probably because they're the only entity that interacts with all of these OEMs and had enough leverage over them to force Secure Boot adoption in the first place.

It's not exactly new for Microsoft to slide themselves in somewhere and become the "standard" before anyone has really thought about how terrible their products are.

It's for your own security, duh ;)

I saw 2-3 flavors of this news. None of them include a basic “how do I check if I need to do anything” guide that a linux newbie can do.

On my Fedora machine I was able to run

    mokutil --db --short 
To check my secure boot keys. As long as there's 2023 Microsoft keys you should be fine. Otherwise, my understanding is that you just need to update your firmware, but please somebody correct me if I'm wrong.

> The KEK updates are going out at ~98% success, and db update is ~99% success

glad to see the opt in fwupd analytics being so useful for something like this

Not envious of the running around contacting vendors they must of been doing on such short order.
