Status is something I'm trying to better understand. It solves the P2P problem of offline messages, but I haven't tried the mobile version to measure battery consumption. I would assume the battery usage is better because Status doesn't require to be constantly online.
I think there needs to be a mind set change for these types of apps. The big shift is to refer to these apps/platforms as decentralized/distributed. Decentralization/distributed includes messaging + currency + websites. Status is also built with Ethereum. So if they have the technology already built, it would seem logical a lot of these apps/platforms are going to include similar crypto/blockchain features. And if you don't like the dapps and wallet, you can disable the features in the app. So far I haven't seen a downside.
This is a good article. A lot of other apps have the same problem. I think it is important that apps have a security threat matrix.
Many people don't realize what is really private, and what isn't. As in a phone conversation, it isn't known what you are talking about, but who you are talking with is known. Is that the full definition of privacy? No. People also don't full understand how metadata can be collected and used. Many people don't understand the risk of a server being hacked. If a server can be blocked/censored, I would imagine a server be spoofed is plausible too.
Many people hear "secure" or E2EE. But they do not realize that applies to the transmission of your message. That doesn't mean it is stored on your device encrypted and secure, nor does it mean stored on someone's else device is encrypted and secure. Some say it isn't necessary because if your device is compromised, then so would any app security. But I doubt those same people leave their password database unencrypted.
