I was pretty disappointed when I learned one of my contacts on Matrix was receiving my messages on his Gmail. That's a feature I would rather the client to not even have so people don't accidentally enable it. I hope it won't take too long for a more privacy-oriented client than Riot to appear. The best thing right now is MiniVector, which is a stripped down Riot fork with fewer permissions required: https://github.com/LiMium/mini-vector-android
Interesting concern - I'm thinking I'd like the various clients to alert me back - as a message sender that the messages were being auto forwarded to a non secure place like gmail - of course I think the option to turn off notifications should be possible on both ends.
That's a good idea. The important thing I think is to create a culture of privacy-preservation around the whole Matrix ecosystem so that features like that make it to the various clients.
You were pretty disappointed when you learnt that recipients of your messages can do whatever they want with them? And your solution is to remove the feature altogether?
How about removing the ability to copy text? Or the ability to take screenshots?
I think the point of the parent is that removing forward to email would only give you a false sense of privacy, as there are several other ways to record received messages.
