When you have mobile wallet regardless of how works (server backend or spv) google/apple knows you using bitcoin. Dojo will remove reliance on server so that's better for sure. On the other hand i know what you saying...

Lots of anti lite client shit flying around recently. Total denial of reality as it is lived on the street, imo.

Google/apple and mobile phone architecture is spyware galore. Gsm chip for example is connected to memory bus and can read any memory location. That Librem phone trying to do things right both hardware and software wise.

Whether or not a component is part of the SoC isn't directly connected to whether or not it's isolated. Separate chips often have DMA, and SoC components usually have better IOMMU configuration.

The claim you're repeating is incorrect. It's a falsehood propagated as part of marketing for products that are making a dishonest attempt to distinguish themselves from existing mainstream devices while they are objectively delivering hardware offering less privacy and security.

What do you want broken down? The claim you're repeating about cellular basebands is untrue. Many hardware components typically have DMA access, including off-die components like Wi-Fi, and it doesn't mean they aren't isolated. It depends on the IOMMU and driver implementations.

Did you have this discussion with ? I would love to hear their response. It's interesting topic and opinions are polarizing.

It's not my opinion that the statement you're making about basebands is untrue. A component being on the SoC doesn't mean it isn't isolated. A component being on a separate chip doesn't mean it is isolated. Those are objective reality is that it depends on the implementation.

SoC components tend to be among the most well isolated. Components like Wi-Fi that are rarely part of the SoC and yet often have DMA access tend to be those that are the most poorly isolated. Drivers also need to treat components as untrusted which Linux drivers often don't do.

It's wrong to portray mobile as a different situation than desktops and similarly to portray mobile basebands as an extremely special case. A desktop CPU is already a vastly complex system of hardware, microcode and firmware, and there are many other components in a system.
A laptop or desktop will often have dozens of different processors effectively running their own operating systems. The main difference with phones is that more of this is provided by a unified SoC from one company with shared security work, rather than many different companies.

There was discussion while back about librem to provide security by isolation like qubes os. Arguments against were cpu hog and bad ux. Not sure was it for laptop or phone...

There is valid criticism in what you are saying. Would love to hear response from . It is educational.
