Secure boot does not improve your security at all - let me remind you that a long time ago they even found a way to bypass BitLocker encryption, the hole in which was closed only in the latest updates and this is only one known "tab."

SecureBoot is needed by corporations (and the fools who naively support it) to create a worldwide digital concentration camp, where there is no right to own software and machine control.

Soon, the majority of the stupid population will be denied the right to have root rights (as is now happening en masse with smartphones - even at the request of the owner, manufacturing corporations refuse to allow them to unlock the bootloader, which directly violates property rights and the owner's right to fully control their property) - they They won't even be able to turn off advertising (the dumbest and simplest common case of what this deliberate trend will lead to) through anti-banner plugins in browsers.
