Not if they want to operate in the United States or have access to our banking system. You don’t get to pick your jurisdiction and then operate globally. You’re obligated to follow the laws where you want to operate.

I wonder how this affects nonprofits like Matrix/Element and Signal. What can they do with them? Gangstalk their developers? Coerce big tech to ban them from their appstores?

The design of these decentralized/federated platforms is specifically so they can't easily coerce their owners into disclosing incriminating information. In some sense, it's similar to how Bittorrent implicates it's users.

Now I just have to get my friends and family to use Signal.

I have been trying to get people to install signal for 2 years. No one has budged.

The day facebook went down for some hours I got phone calls.

That is correct. By default all messages sent over Telegram are stored permanently in their servers unencrypted.

Not exactly. Non-secret chats are stored encrypted on Telegram's servers, and separately from keys. The goal seems to be to require multiple jurisdictions to issue a court order before data can be decrypted. https://telegram.org/privacy#3-3-1-cloud-chats https://telegram.org/faq#q-do-you-process-data-requests

"Not exactly" means "completely incorrect" now?

Telegram doesn't store your messages forever and they are encrypted and seizing the servers won't allow you to decrypt them unless you also seize the correct servers from another country

If i'm reading this page correctly, AMD is working on something that would allow you to run trusted code that not even someone with physical access to the hardware could read (without breaking this system). https://www.amd.com/en/processors/epyc-confidential-computin... And this tech is already implemented by GCP: https://cloud.google.com/confidential-computing > With the confidential execution environments provided…

Then you only have to trust that AMD did not accidentally or intentionally introduce a bug in the system. Remember Spectre? Remember all the security bugs in the Intel management code? You also have to trust that AMD generated and have always managed the encryption keys for that system properly and in accordance with their documentation. And are you even sure that you’re actually running on an AMD system? If the syst…

puts on tinfoil hat

You'd also need to consider AMD's management engine, the Platform Security Processor. If we're really slinging conspiracy theories, AMD processors are likely just as backdoored as Intel one. I don't mean to be grim, but I think it's safe to assume that the US government has direct memory access to the vast majority of computer processors you can buy these days.

They left off one very popular messenger, SMS: * Message content: All * Subpoena: can render all message content for the last 1-7 years * 18 U.S.C 2703(d): can render all message content for the last 1-7 years * Search warrant: can render all message content for the last 1-7 years * Vague suspicion plus a small fee to the carrier: can render all message content for the last 1-7 years

There's also:

* Law enforcement simply asks nicely: can render all message content for the last 1-7 years

Well, who cares when all they need is to use something like Pegasus to obtain full access to your phone simply by sending you a WhatsApp message (without having you even open the message). Knowing how well guarded IOS is against app developers, I wonder what kind of zero-day would suddenly turn a message received in WhatsApp to full system access. I think NSO found a WhatsApp backdoor, not a zero-day bug.

Whatsapp is owned by facebook, not by apple. I don't think Apple wants to share a backdoor with facebook.

I don't know any detail of the whatsapp vulnerability that NSO exploited.

So if you have something to hide, don't use iCloud backup. And Whatsapp will give them the target's full contactbook (was to be expected), but also everyone that has the target in their contact list. That last one is quite far reaching.

> if you have something to hide

Most people don't realize that most people have something to hide. The USA has so many laws on its books. Many of which are outright bizarre[0] and some of which normal people might normally break[1].

And that's only counting current/past laws. It wasn't that long ago a US President was suggesting all Muslims should be forced to carry special IDs[2]. If you have a documented history being a Muslim, it could be harder to fight a non-compliance charge.

It's incredibly disheartening how difficult it is to get most people to care about digital privacy.

If this is what it takes to keep us safe, I and most americans are ok with it. We live in dangerous times. The US has a balanced criminal justice system -- as long as due process is preserved privacy from the state should not be a major issue

How does them reading my messages keep me safe, though?
