       | It seems there's nothing on Signal's blog as of yet, but the
       | project's git repository was tagged with v7.0.0 yesterday and we
       | can see from the commit history since the previously tagged
       | version (v6.74.4) that there will be a setting to hide one's
       | phone number [1], as well as disabling the previous default
       | behavior of advertising that one is on Signal to all of their
       | contacts already using it [2].

       | 
       | My phone is considered "desktop" by Signal, and it doesn't work
       | without connecting to a "real" phone.

       | It's good enough when I don't need a number to sign up at all.
       | Unfortunately they're not there yet. So for now.. meh

       | Without that it's just a slightly more private WhatsApp.
       | 
       | In fact I wish we could move to another kind of identifier than a
       | "phone number" for things like this. It's probably pretty region-
       | dependent but personally I never use my phone to actually make
       | phone calls or text. All my voice, video and messaging traffic to
       | friends goes through apps, though the number is unfortunately
       | still used as an identifier. Unfortunately, because if I let a
       | number lapse I lose access to the whatsapp and telegram accounts
       | related to it. This way it makes it hard having multiple
       | accounts.
       | 
       | I'd prefer if mobile providers would just become a dumb data pipe
       | the same as landline providers have already become. My Spanish
       | provider still forces me to take a "landline" with my internet
       | but I don't even have a phone connected to it.

           | messaging threat models (I don't mean that as a value
           | judgement).

             | The same is likely true of Signal, no? Traffic analysis on
             | AWS' edge would tell you precisely who is talking to who,
             | and user identities are tied to legal identities via phone
             | numbers. Maybe Signal doesn't store this data serverside,
             | but there are entities with both the capability and
             | motivation to obtain it. I bet there are Signal XKEYSCORE
             | selectors.

           | problems arose. By switching from Matrix to Session, by
           | switching to Signal, where we are now, fewer problems arose

         | Signal will not publicly admit that, but they are using phone
         | numbers as a cheap anti-spam measure. If anyone can sign up
         | with an email, you will have same spam problems as with email,
         | and will need to implement some spam filtering, and so on.
         | 
         | It's harder to spam with phones. Although, as they now do in
         | Burma, they can just kidnap a lot of people from China and
         | India and keep them as slaves and make them send spam from
         | phones. But anyway that's a different story

         | 
         | They are not even comparable. WhatsApp does not encrypt
         | metadata at all, which is the most interesting information you
         | can leak.

       | all of their Signal chat history (photos, etc) are gone.

         | Heh. I have the opposite problem. I'd like a way to have Signal
         | auto-delete conversations and media from my device after a
         | certain amount of time.
         | 
         | Yes, there are auto-delete options, but those apply to the
         | group/chat as a whole, and other people in some of the groups I
         | belong to want to keep their chat history. I'm not totally
         | opposed to them doing so, but would like the option to just
         | delete my copies.
         | 
         | (Signal uses more space on my iPhone than all my other apps
         | combined, and I've had problems with upgrades being blocked
         | because there wasn't enough space remaining to install them.
         | Manually deleting hundreds of photos from individual groups to
         | make room is _such_ a pain in the ass.)

           | Large group chats should have an expiry of one week or so,

           | Unfortunately the best way to delete those old messages in
           | your local chat is to delete the conversation and rejoin it.
           | 
           | Admins really should have a "purge all history older than X"
           | option. They let you do it one by one manually, but it's
           | basically impossible to automate, and doing it manually is
           | super tedious.

         | So you're looking for a feature where someone can hit a button
         | and get a clear text export of all the encrypted chat history
         | on the phone? You do understand why that feature doesn't exist
         | right? Backup utilities are regularly abused by criminals and
         | other bad actors to harvest private data.
         | 
         | If you want to record all of your chat history with someone and
         | keep it around forever, Signal is not the right tool. Signal is
         | for private communications, and I'm glad that people on the
         | other side of conversations with me can't just export
         | everything with a button press. That would be a massive
         | violation of trust.
