Can anyone give an ELI5 on how hardware attestation works or is implemented on current OSes?

I don’t disagree with you generally, but any open source software can contain malware if no one is actually looking at the source code.

When was the last time you audited the Brave code?

lol no not at all. They are franchises, not fronts for the manufacturer. Everything you said is as wrong as can be.

Like the other person said, you are confusing the dealership and the manufacturer. This is the equivalent of those people that yelled at the teenagers working at chik filet. The dealership will just say they don’t create those rules and you’d have to take it up with the manufacturer, then ask you to leave. If you don’t leave and act like a jerk, they’ll just call the cops and have you escorted off premises.

Thank you, I will check them out
