Not sure why downvoted. I run blobless coreboot for precisely this reason. My only regret is not being able to find newer x86_64 gear that supports it. OTOH you can still buy in-production arm64 boxes that boot with zero blobs (RK3399).

One of the cloud vendors created UEFI.

Then they know full well how bad it is!

*Jokes aside, I think Intel created UEFI (for Itanium?), not Microsoft?

The consortium has AMD, Intel, and Microsoft listed as contributors, so even if they didn't initially create the thing, they had a hand in it. The executable format used for UEFI is PE, which is telling.
