How dare you suggest Mark Zuckerberg is a hypocrite after said "Privacy is no longer a social norm", and then bought all houses surrounding his one.

Yeah, it is likely that he was just checking up on the competition. I wouldn't be surprised if turned the narrative on this by saying something like the following: "I was curious to check it out.. it wasn't very good, so I reverted back to Messenger/Whatsapp." IIRC, he made similar comments when he was spotted using G+. Disclaimer: My views are my own (and not necessarily shared by my employers).

It doesn't seem like you are aware that WhatsApp hired Moxie Marlinspike, the creator of the Signal encryption protocol, to re-implement it for WhatsApp. AFAIK it is still used in WhatsApp today. I will take this moment also to mention that "re-implement" isn't exactly right in that they modified the protocol slightly to allow for someone in control of the administration server to change a user's private key without…

> they modified the protocol slightly to allow for someone in control of the administration server to change a user's private key without their knowing, so that the admin can decrypt the E2E communications using the known key.

You mean, no-longer-E2EE.

Maybe its mentioned in one of his earlier comments on this platform.

Funny comments, but jokes aside, I think we're missing a very obvious reason why he has signal. Mark most likely has contacts that are super high up in governments and coorporations who use signal since they can't trust any other app. People who say that he just tested out competition, I think you guys underestimate his technological knowledge and his resources waaay too much. If he wanted to do that he could have easily ordered someone to get him a clean phone with a sim card not linked to his name and let that device sit on his desk for testing.

I’m not totally convinced by the narrative that Mark doesn’t trust his own tools so he prefers Signal. He has tape over the camera of his own computer in Facebook HQ

Everybody should have a shutter over the camera, just to protect from blunders and misclicks. No matter how you trust your software, some malware may want to activate it, especially at a high-value target like Zuckerberg (or Bezos, or Nadella, etc). Alas, microphones are not as easy to deactivate.

Covering a camera always seemed like unjustified paranoia for me.

If someone can access my camera and spy my unkept beard, why won't they also be able to access my keyboard and spy my main email account password?

Actually, they are. Just grab headphones with microphone and use scissors and keep the jack in.

Don't know about laptops but on recent desktop motherboards the jack detection and output/input switching is done in software. Probably the case on many laptops too. So this approach shouldn't be considered a "hardware switch" as it's still possible to capture audio from another mic even when a headset is plugged in.

On both of my XPSs I can switch to internal or external mic regardless of a headset behind plugged in, so the snarky suggestion to use a cut-off headphone jack is misguided and won't work on many modern laptops.

I would have thought that Mark of all people would have complete faith in the privacy of Facebook Messenger and WhatsApp. Very curious indeed.

I would imagine Mark of all people to at least do some amount of competitive analysis. It's like being surprised Elon test drove a BMW i3.

If Elon test drove a BMW i3, we'd be hearing about it direct from him via a snarky tweet.

Isn’t a bit of a privacy flaw that signal exposes who uses the app by phone number?

Privacy flaw and a security flaw: it is feasible to take over somebody's phone number through social engineering attack on the phone co's tech support. The tech support has ability to issue replacement SIM cards for users, and if an attacker socially engineers them to send SIM card with your number to them, it's a game over for you.

That is aside of the obvious problem of phone numbers being recycled for re-issue after having been abandoned for a stretch of time.

And what was the suggestion? The flow of information is (You typing → IME converts key presses into text → Signal receives text) so Signal can't do anything to prevent a malicious IME from sending the text elsewhere. The best they could do is raise users' awareness that Signal won't protect them if there's spyware with privileged access on their device, and that their IME might be such spyware.

Mainly the OS has security options to prevent IME network connections that aren't always on by default, but users can enable them. (They might be off because it disables some features that need internet access.) IIRC there was also some Android API that could be used in the app to help, but I don't remember what it actually did atm.

Perhaps your man the incognito keyboard option? Signal uses it, but no API I can imagine will protect against a malicious IME.

Worse still, even if you block IME internet access on a device with a factory-maliciois IME, they could just upload the data using some other service on the device.

Installing a known-good IME seems like the only fix I can think of?

because 1 is not an opinion but a fact. and probably a fact he probably disagree with, like you

people don't care about privacy but it's not exactly his fault. then his job is to capitalize on it. why would he care. you would probably do the same ..
