And what good is the phone when 3 switches are off? You think that people buy a phone with a "mic killswitch" expects to have to turn off practically everything including internet to make sure that their mics aren't snooped on?

Does that really sound like a functioning "killswitch"?

The mind, it boggles.

On a long enough timeline he'll probably cite this comment chain as proof you were unable to respond to his concerns, like everyone else who's ever tried.

[TommyTran732]

Oh he's already done that when I explained to him how stuff like PureBoot has circular logic and doesn't actually work on Qubes forum already.

Unfortunately he will just ignore every single counter argument ever made and blindly believe these companies because their marketing material has "freedom" and "FOSS" in it.

On Qubes forum, you had replies from far more knowledgeable people than me. You never could answer to them. You only talk about the lack of security of Pureboot and never showed the code breaking it. "Talk is cheap, show me the code".

> You never could answer to them.

I did reply to them plenty of times. Here you go doing the exact same thing again - ignoring 100% of what's being said, then claiming "no one can respond".

> You only talk about the lack of security of Pureboot and never showed the code breaking it.

If you think a piece of code is needed to understand why it's a joke, then I don't even understand what is wrong with you. LMAO. The whole thing is conceptually botched, and they pretty much admitted as much.

1. Boot block performs measurements of itself, its settings and everything down the chain for attestation.

2. There's nothing protecting the boot block.

3. A malicious boot block can lie about measurements.

4. If the goal is to defend against an attacker who tampers with the BIOS chip - then it fails at doing so miserably because an attacker can just use a boot block that lies about the measurements.

Seriously, what good is showing you the code if you don't even conceptually understand how the thing works?

You know, there is a famous saying: A farmer does not need to know how to lay eggs to know whether an egg is good or bad. In our case, the egg is already rotten from the get-go. This is not a "Ohhh something has such bad code I can attack it using XYZ method, wait and see!" situation. This is a situation where "Your logic doesn't even make any sense to begin with."

Perhaps, just perhaps, you can benefit from just spending 5 minutes thinking a bit about how the whole thing actually works at a very high level and read what I said above.

Thank you for your kind advice, but I prefer to trust a developer of Heads and many Qubes contributors instead of a loud Internet commenter criticizing everything and everyone.

[TommyTran732]

The developer of Heads admitted that if someone tampers with the boot block and falsifies the measurements Heads cannot protect the device right on the Qubes forum. Why won't you listen to him then? Is he not trustworthy enough for you?

Unless it's Qubes OS team members' valid, rigorous and consistent criticisms of Purism over the years, that is.
