Yes but I'd say some people (me) like WhatsApp because of the privacy and end-to-end encryption. Email i assume is less private but still more private than a public post.
Imagine someone puts all the Signal messages someone else sent them through an AI. I dunno. I think problem is most AI doesn't work like Confer.to, also by Signal's founder.
People have been screenshotting conversations, saving them on their phones, and sending them to friends over text for as long as there have been conversations to screenshot.
The entire concept of conversations being "secure" is only as good as your ability to trust the other party isn't doing something insecure with them (and that yours and their devices are, themselves, as secure as you think they are. Which they generally aren't.)
All of which is to say, it's security theater and always has been when applied to real life situations.
There's a difference between small scale screenshotting certain conversations, and wholesale vacuuming up everything in to the AI machine.
Except now there’s not. The fact is, when you tell somebody something, what they choose to do with it is out of your hands. Unless you want to start using drm-encumbered systems.
There's still a difference between a person deciding to share one or a bunch of messages they receive --usually I know the people I write to, so I know more or less what to expect-- and systematically uploading received message to some AI. Fine if they do it locally, not fine if the messages I write end up at Google, OpenAI or anybody else.
This is unrealistic. Hardly anyone who is going to feed their own messages to an AI is going to pay attention to whether it’s local or cloud based. Get real.
Well, then not at all...
So you're saying DRM is good now?
No, I’m saying when you send messages to someone else, they are out of your control. Trying to fight that with DRM would be folly.
