I think it means SecureBoot sucks.

The Secure Boot signature of the old bootloader had to be revoked due to a security vulnerability which was discovered in that bootloader. There is no fixed time limit, but it is possible that other images share a similar fate when their bootloaders are found vulnerable again.

The theory is sound. The implementations of it, especially the shim idea, sucks. This could be a useful security feature if used properly. Just that most of the time it isn't. Kinda like people just turning off SELinux instead of working with it. :P

Not really. The core idea that *someone else* gets to decide what you can and can't run on your hardware is utter bullshit. As long as the only "people" who get keys are multi-billion dollar corporations, the concept will remain nothing but a failure of a scam that's all about restricting user choice, not security.
