This isn't a blow to real security, just to DRM and treacherous computing. There's no legitimate security from "Secure" Boot.

"Evil maid" is a generic descriptor for any number of attacks that can be performed with physical access to a device.

https://en.wikipedia.org/wiki/Evil_maid_attack

"The name refers to the scenario where a maid could subvert a device left unattended in a hotel room – but the concept itself also applies to situations such as a device being intercepted while in transit, or taken away temporarily by airport or law enforcement personnel. "

Still, how real of a threat that is for 99% of computer users?

And law enforcement will have a device to bypass most devices security

What makes you say that and how is that an excuse to do nothing?

To prevent against a evil maid attack you would need to encrypt your drive

In case of a malfunction, you risk loosing all your data

Threat actors and law enforcement can bypass it
