The name “Secure Boot” is such an effective way for them to guide well-meaning but naïve people's thought process to their desired outcome. Microsoft's idea of Security is security from me, not security for me. They use this overloaded language because it's so hard to argue against. It's a thought-terminating cliché.

Oh, you don't use <thing literally named ‘Secure [Verb]’>?? You must not care about being secure, huh???

Dear Microsoft: fuck off; I refuse to seek your permission-via-signing-key to run my own software on my own computer.

Agreed.

Also Secure boot is vulnerable to many types of exploits. Having it enabled can be a danger in its self as it can be used to infect the OS that relies on it.
