  • When Whatsapp was sold to Facebook in 2014, they had 55 employees. Considering the app had considerably less features and did not focus so heavily on encryption and privacy, Signal can be considered even leaner than Whatsapp.

    Now, for the actual breakdown, they have at least the following technical teams: desktop, android, iOS, server, calls (ringrtc), core (libsignal). If we assume a team has usually 5 people (manager, Sr SWE, Jr SWE, QA, maybe PM), that’s already 30 people. On top of that, they have an in house support team (don’t know the size but I wouldn’t be surprised if they have 10ppl on the payroll considering the number of signal users) and management (CEO, CTO, CSO, VP), which will quickly add up to around 50.



  • Android is Linux-based but it has a modified kernel. It might be subtle but the entire design philosophy of Android is mobile first, which is very different of Ubuntu or Arch.

    But there the similarities end. AWS created custom firmware and ripped out anything remotely related to running a consumer device, replacing it with software designed solely to create a secure connection between the device and desktops running in the Amazonian cloud.

    If they are going to rewrite the firmware, remove most of the features, why even bother with an OS designed for touch screens and partially written in Java? Can’t they fork one of the 22 ARM Linux distributions?





  • The article says it’s to limit spam. I don’t feel platforms like Lemmy (or the other platform) are particularly spammy though. On the other hand I get a lot more spam on Whatsapp, even though it’s phone number bound.

    Signal is pretty good in terms of limited spam, but I’m curious about the impact if they A/B test the removal and see how much spam would arise. Obviously that could only be implemented after they remove the need to add contact via phone number.




  • Sorry I misframed it. I mean that since there’s no need to reveal phone numbers, there could be an opportunity for spammers to increase spam by creating many accounts, and Signal should preemptively find ways where such spams could be reduced. However, I realized after posting that the article says we still need to sign up to signal with a phone number. However, there’s still the risk of impersonation (by writing someones username with tiny changes) and people trying to add vulnerable users by username (which they might be using on other platforms) instead of phone number.
