alt Hacker NewsWhat are you talking about? This has nothing to do with general purpose computing and everything to do with allowing you to authenticate the parts of the Linux boot process that must by necessity be left unencrypted in order to actually boot your computer. This is putting SecureBoot and the TPM to work for your benefit.
It's not propaganda in any sense, it's recognizing that Linux is behind the state of the art compared to Windows/macOS when it comes to preventing tampering with your OS install. It's not saying you should use Windows, it's saying we should improve the Linux boot process to be a tight security-wise as the Windows boot process along with a long explanation of how we get there.
Secure boot is initialized by the first person who physically touches the computer and wants to initialize it. Guess who that is? Hint: it's not the final owner.
It's only secure from evil maker attacks if it can be wiped and reinitialised at any time.
