They don't use Signal for the encryption; they don't know what encryption is. They only use it for the disappearing messages.
@evan Yeah, that's the take, right there 👆
@evan WhatsApp also has disappearing messages. Even email can have that.

Disappearing for you and the recipient, but not for Meta.

> Even email can have that

It definitely can't.

@evan

@strypey @albertcardona @evan That would indicate they are using it for encryption, to a degree, because they actually trust it isn't backdoored...

Having said that, it's almost entirely speculation, regardless, as they're never going to address it transparently... their intent is not something they'll ever make public...

Wire has a disappearing messages feature as well FWIW. They come with a risk of creating a false sense of security, if people don't understand their limitations;

Disappearing messages features can’t actually guarantee message deletion, but what they do offer communicators is even better.

AFAIK there's literally no way to be sure both the server(s) and the app(s) at the other end obey your app's instructions to destroy the message. Servers don't matter so much if the messages are reliably E2EE, but ...

Maybe Reproducible Builds offers a solution here? There could be a way for your app to query the receiving app, to check it's compiled from source code that implements message destruction. Just thinking out loud here ...

@evan people forget / don't know how easy it is to screenshot a conversation for posterity
@vitriolix screenshots are easy to fake, and thus easy to deny.
@evan I'm waiting to hear about a migration to Snapchat.
@evan and of course some can take screen shots before the message disappeared.
@evan They trade all the time regular folks use to consider logic, practicality, and ethics and use it for grifty, climber, self-justification ideation.
@evan @briankrebs I hope that when they make a movie out of this that there are still people around who recognize the absurdity of it all. Kids are growing up in this situation without reference points and we grownups need to make it clear that this is not normal.

@Elephant @evan @briankrebs

It's truly sad.

Imagine being born early enough, so that in the Bush 2 era, when you're sapient and the president isn't, it's - normal - for you that he's an imbecile - but Republicans aren't complaining -.
Obama is smart, they whine, Orange T ver 1, another imbecile, no whine.
Biden, more political whining, then Orange T again, an imbecile, but no whine.

You're right; intelligent presidents are almost a myth that kids wouldn't believe even exist half the time.
😬

@evan it would be extremely "convicted of tax evasion" if what these goofuses ended up going down for was violating record keeping laws.
@evan Its not about screensots. Its about not keeping records of what these people do while governing. Which is illegal.
Evidence of bribes, quid pro quos,all sort of crimes won't be recorded.
Neither for law enforcement, historians or the press, (OK sometimes).
Most of it will never see the day, the very reason they have been using Signal so so security and its disappearing messages.
No accountability.
@evan And it is outside of reach of the US Archives and Freedom of Information Act. Don't need to be burdened by those pesky rules and regulations. I had a right-wing member of the school board I was elected to constantly use text messages rather than his school system issued email address previously for that reason.

@evan

Yeah, and they don't even understand how disappearing messages work (or don't, in this case.)

@evan

The other reason that they use it is likely their fear of the Deep State. I.e., of competent, ethical public officials.
