How good you feel good about your privacy using apps such as Signal? (lemmy.wtf)

Convincing people to use apps such as Signal is hard work and most can't be convinced. But with those you manage to convince, do you feel happy to talk to them on Signal?

The problem is these people use Signal on Android/IOS which can't be trusted and IOS has recently been in the news for having a backdoor. And it has also been revealed that american feds are able to read everyone's push notifications and they do this as mass surveillance.

So not only do you have to convince people to use Signal which is an incredibly difficult challenge. You also have to convince them to go into settings to disable message and sender being included in the push notifications. And then there's the big question is the Android and IOS operating systems are doing mass surveillance anyway. And many people find it taking a lot of effort to type on the phone so they install Signal on the computer which is a mac or Windows OS.

So I don't think I feel comfortable sending messages in Signal but it's better than Whatsapp.

These were some thoughts to get the discussion started and set the context.

They ask the push providers (Apple/Google) for data on the push token from e.g. a messaging app. This way they associate the account from an app with an identity.

Very overlooked point. You can find privacy guides online but very few even suggest that FCM etc. might have privacy issues, let alone explain exactly why. It seems this has already been used by law enforcement in the past: https://www.wired.com/story/apple-google-push-notification-surveillance/

The Molly-FOSS fork of Signal (which aims to be even more secure/private) actually supports self-hosted push notifications using UnifiedPush.

I also found this comment:

As far as I know, FCM on Android can be configured to use a notification payload (which is piped through Google's servers). But for a release app this is discouraged, especially if you are privacy conscious. An app would normally use FCM to receive a trigger and look up the received message from the app's own backend. See here for more information.
