Google just announced that all RCS conversations in Messages are now fully end-to-end encrypted, even in group chats. RCS stands for Rich Communication Services and is replacing traditional text and picture messaging, providing you with more dynamic and secure features. With RCS enabled, you can share high-res photos and videos, see typing indicators for your…
It’s E2E, E2E isn’t really something you can be sneaky about unless you roll your own encryption and then make claims about it totally being safe bro
They, however, run the app you are using to type everything, the keyboard you are using to type everything and the os you are using to type everything. If they want something, they don’t need to look at your in flight messages.
The trust doesn’t even have to be in the encryption, they could very well use the same signal protocol. They would only need a copy of the keys you are using and you wouldn’t even know… That’s the problem with closed source programs, there is no certainty that its not happening (and I’m not saying it is, I can’t prove it, obviously, but the doubt remains, we need to trust these companies not to screw us over and they don’t really have the best track record in that…)
As if you’re any more comfortable with open source software, actively vetting the code, building it yourself, running your own server.
For all you know, Signal keeps a copy of your keys, too. And happily decrypts everything you send and sells it to russian data brokers for re-sale to advertisers.
There is a post gathering all security audits performed on Signal messenger:

And anybody can double check it, because it’s open source. And not only is it open source, but they have reproducible builds which mean you can verify that the apk you download is the same version as is hosted on github. They also have server code published. Pretty rare. Additionally experts in the field themselves endorse signal.
Your point is valid for many projects, as open source is not a guarantee for security. But signal is a pretty bad example for that.

With a closed source app? Of course you can. How is anyone supposed to know what keys you use for encryption? Doesn’t even need to be a remote one - just the key generation be reproducible by the developer.
