Serious question, really? Like when you're just having beers with your friends? Why? Does it make your friends feel uncomfortable? What's the benefit to you?

I mean work/project meetings, not "social gatherings". Essentially, when an encounter serves more that just a social purpose and information is shared, I either want a record of that meeting (information) to be kept or for that meeting not to take place at all if there is nothing noteworthy (again, does not apply to meetings that have a predominantly social function).

Okay that I get, but I don't understand recording every text since that's more akin to recording social gatherings and private conversations.

I mean, from the perspective of the crypto it doesn't matter. But it defeats the point of building a forward-secret system. Think of it like this: if I'm an attacker that breaks into the forward-secret chat app on your device, and you have kept a perfect record of every conversation you've ever had using that crypto system in _the same place you keep your identity keys_, then does it really matter whether the messagi…

The way I like to think about it:

If you had a way to keep your old messages safe then you could of just used that method to protect your private key.

It's not reasonable to expect it to be a defacto messenger if you can't save chat history. Full stop. If I want a conversation to be private, I set expiring messages, for the rest of it, I want to be able to go back and reference things all the time. Whether it be digging up a song link I sent a buddy, or looking up the address someone sent me a week in advance. If they can't operate or are unwilling to operate under…

Be a cool feature if they let us encrypt chat history in a local file.

Am I missing something? That's how their backups work currently

Chat history isn't immediately at odds with PFS. As I see it PFS first and foremost is for protecting messages in transit. This is to prevent dragnet-style surveillance.

Chat history means giving up some measure of at-rest security, but it has no impact on the in transit part. Personally I also think some compromise of at-rest is a reasonable trade-off for a lot of consumer contexts because physical capture of your device already is basically game over.

The problem is it doesn't work at all on iOS, and there's no way to sync between iOS >> Android or iOS >> PC.

Spending the weekend building Signal for iOS so I can try to dump message contents before I send an iPhone in to Apple. Just astounding that there is deliberately no way to backup messages (which has be available on Android for some time). Definite love-hate relationship with users, which I fully reciprocate.

So great job getting WhatsApp import working. But too bad you can't export anything from Signal. Dark patterns ahoy.

"As we stand now even Signal is not safe because of the business model." ? Ok, good, but you do realize that this is the most existential concern of them all? Why does FB so aggressively pursue personal data? For advertising. Because 'that's the business model'. Do you think that any entity would be in that position if say, people were willing to actually pay $3/month for what seems to be very obviously a highly usef…

Yeah, and that's the major issue with Signal/Telegram. They also have to pay the operational costs at the end of the day. Apple's services can be ad free because they hide the cost in the cost of phone but that is extremely anti competitive. A user on an iPhone will have a hard time rationalizing for Signal which says $3 per month when he looks at iMessage and that is free

Telegram has infinite history while Signal has PFS. So the costs are not the same at all.
