Very, I know people who work there, they open sourced their crypto engine [1]. They also struggle with people using WickrMe for bad stuff because of how little info they collect from users (no phone required, true e2ee encryption, and so on...) [2].Own by Amazon doesn't imply that have spyware embedded, unless you can prove, not defending Amazon by any means, there is plenty to criticize and condemn about them, I'm just stating facts. 1- https://github.com/WickrInc/wickr-crypto-c 2- https://www.cnbc.com/2022/06/10/wickr-amazons-encrypted-chat...

It looks like some of the core parts aren't closed source (but definitely not open source). For example: https://github.com/WickrInc/wickr-crypto-c

https://github.com/WickrInc/wickr-crypto-c ## Linux ### Linux Requirements - CMake 3.1 or higher - Clang - OpenSSL => 1.0.2 (Optional) ### Linux CMake Configuration The linux build can be configured using the standard CMake flow with a few options ``` mkdir build cd build cmake -DBUILD_OPENSSL=true \ -DCMAKE_BUILD_TYPE=Release \ -DCMAKE_INSTALL_PREFIX=USER_INSTALL_LOCATION ../

I mean, they're both open source* e2e protocols. The primary difference is signal has a lot of cryptanalysis cred. It basically comes down to your opinion on which you prefer. *have not investigated myself, but found their repo which implies as much. https://github.com/WickrInc/wickr-crypto-c

Whilst not the same as mentioned in TFA, I noticed in Signal that if you allow it access to your contacts it will tell you how many of your contacts are already on Signal. I understand this is useful from a usability/discoverability aspect, but from a privacy perspective I have no reason to be made aware of the fact that one of my old bosses who's number is in my phone is on Signal and neither should they know that I am on Signal for the same reasons (or lack thereof). What's worse is there seems to be no way to opt-out of this behavior. I can deny Signal access to my contacts, thereby not knowing which of my contacts are on Signal, but that doesn't stop the other party from knowing if I am on Signal if they have given Signal access to their contacts. It's not farfetched to consider a world where an oppressive regime may outlaw the use of
