Thats a different tech. End to end is cut and dry how it works. If you do anything to data mine it, it’s not end to end anymore.
Only the users involved in end to end can access the data in that chat. Everyone else sees encrypted data, i.e noise. If there are any backdoors or any methods to pull data out, you can’t bill it as end to end.
You are suggesting that “end-to-end” is some kind of legally codified phrase. It just isn’t. If Google were to steal data from a system claiming to be end-to-end encrypted, no one would be surprised.
I think your point is: if that were the case, the messages wouldn’t have been end-to-end encrypted, by definition. Which is fine. I’m saying we shouldn’t trust a giant corporation making money off of selling personal data that it actually is end-to-end encrypted.
By the same token, don’t trust Microsoft when they say Windows is secure.
Its a specific, technical phrase that means one thing only, and yes, googles RCS meets that standard:

How end-to-end encryption works
When you use the Google Messages app to send end-to-end encrypted messages, all chats, including their text and any files or media, are encrypted as the data travels between devices. Encryption converts data into scrambled text. The unreadable text can only be decoded with a secret key.
The secret key is a number that’s:
Created on your device and the device you message. It exists only on these two devices.
Not shared with Google, anyone else, or other devices.
Generated again for each message.
Deleted from the sender’s device when the encrypted message is created, and deleted from the receiver’s device when the message is decrypted.
Neither Google or other third parties can read end-to-end encrypted messages because they don’t have the key.
They have more technical information here if you want to deep dive about the literal implementation.
You shouldn’t trust any corporation, but needless FUD detracts from their actual issues.
Even if we assume they don’t have a backdoor (which is probably accurate), they can still exfiltrate any data they want through Google Play services after it’s decrypted.
They’re an ad company, so they have a vested interest in doing that. So I don’t trust them. If they make it FOSS and not rely on Google Play services, I might trust them, but I’d probably use a fork instead.
You are missing my point.
I don’t deny the definition of E2EE. What I question is whether or not RCS does in fact meet the standard.
You provided a link from Google itself as verification. That is… not useful.
Has there been an independent audit on RCS? Why or why not?
They can just claim archived or deleted messages don’t qualify for end to end encryption in their privacy policy or something equally vague. If they invent their own program they can invent the loophole on how the data is processed
Exactly. We know corporations regularly use marketing and doublespeak to avoid the fact that they operate for their interests and their interests alone. Again, the interests of corporations are not altruistic, regardless of the imahe they may want to support.
Why should we trust them to “innovate” without independent audit?
The messages are signed by cryptographic keys on the users phones that never leave the device. They are not decryptable in any way by google or anyone else. Thats the very nature of E2EE.

They cant fuck with it, at all, by design. That’s the whole point. Even if they created “archived” messages to datamine, all they would have is the noise.
Or the content is encrypted, but the metadata isn’t, so they can market to you based on who you talk to and what they buy, etc.
Provided they have an open API and don’t ban alternative clients, one can make something kinda similar to TOR in this system, taking from the service provider the identities and channels between them.
Meaning messages routed through a few hops over different users.
Sadly for all these services to have open APIs, there needs to be force applied. And you can’t force someone far stronger than you and with the state on their side.
This part is likely, but not what we are talking about. Who you know and how you interact with them is separate from the fact that the content of the messages is not decryptable by anyone but the participants, by design. There is no “quasi” end to end. Its an either/or situation.
