You think Facebook does not have access to Whatsapp messages ? Would be very surprised if thats not the case.

Facebook doesn't have access to WhatsApp messages. WhatsApp uses the same end-to-end encryption protocol as Signal. We know this is true because the app has been extensively reverse engineered to create these third party clients among other reasons.

Everything is closed source, and you have no idea what is running on their servers, etc, so all your suppositions are worth basically nothing.

Check my reply to the other comment. WhatsApp has been extensively reverse engineered.

It's not obvious. You are uploading a photo to send to a friend, you don't know or expect that where this photo was taken is automatically used by Facebook to target you. Hell, most people wouldn't even know that the EXIF has the location.

I remember sending Apple Live photos to friends when "live" photos first came out. It wasn't 6+ months later that I realized audio was also embedded in live photos. I just never noticed because my phone is always on silent mode. The realization that I was sending audio clips to friends and family along with photos for months and month was... unnerving. It's a problem when tech becomes so complex that the average (or…

Imho there is kind of a responsibility to the user to know what he is doing and what his actions do imply.

If you take an image with a GPS enabled camera, yes that information along others can be saved as metadata.

Sure, tech companies try to abstract the functionalities, making it more difficult to see and understand. Still, this can not be an excuse to just do things not unknowingly.

> By default all your photos are sent to icloud Go into settings and turn off iCloud for photos, keychain and any other app you don't want it to work with. The difference of all of these things is that Apple is doing it to improve its apps for YOU, uploading photos from your phone to iCloud so you can see on other devices, or face recognition to group your photos, keychain copying is used across devices that you've e…

> Apple is doing it to improve its apps for YOU This seems subjective; other companies could claim the same. E.g.: FB says they're trying to show YOU more relevant ads. > The data may be in Apples iCloud but is 'private' This seems more objective to me and a better indicator of actual privacy. Still, we should keep in mind that Apple's goals may change in future and that they might change their approach.

> The data may be in Apples iCloud but is 'private'

But how do we measure that?

Apple went into differential privacy a while ago, which really isn't about privacy, its about anonymisation. Which is not the same thing. Private means that no one else but you[1] can see your stuff

Anonymous means that people can see your stuff, but they don't know who you are. This is different.

[1] well mostly only you

We don't need local solutions, we need FOSS solutions so everyone can see exactly what's going on.

To "see exactly what's going on", you would need to be sure of what's happening on the server, and I don't know how to do that for sure except for the blockchain. Meanwhile, here in the real world, let's stick to the better one of the bad choices we have.

You're making a good point. We can, however, write software that makes certain guarantees on the client side. If I'm the only one with the encryption keys, does it really matter what the server does?

This is the basic idea behind zero-knowledge systems using homomorphic encryption to do very cool things.
