I want to preface this by saying that yes, I know that Instagram is bad. I am planning to get rid of it in the future but as of now I have to keep it for communication with people who are only on that platform.
So I have grapheneOS, use protonvpn (free version), use mull as my browser, and do not have google play services enabled on my phone. I do have some apps downloaded through aurora store such as Instagram, whatsapp, mychart, and mint mobile, but the rest came from f-droid.
I have noticed multiple times that after having private conversations on matrix, I get Instagram content in my feed that is scarily accurate to the conversation I had on the other platform immediately after. I know that things discussed in Instagram direct messages and group chat will give suggested content based on those conversations, but I get stuff that that is very specific to what I have ONLY discussed on matrix and didn’t look up via my browser.
So my question is how is Instagram doing this and what can I do to mitigate the spying it’s doing on my other apps. Thanks.
they encrypt the content, but not the metadata. so Meta might not know what you’re talking about, but will know who do you talk with, how often, where from, for how long, and so on. that’ll often be more valuable for advertisers than the contents of the messages themselves.
More importantly, Meta also has the encryption keys of any WhatsApp conversation.
It’s like a fucking META password manager that unlocks your vault… (…as in your WhatsApp conversations) and locks it when they are done spying, whenever they feel like. Repeatedly.
You have no control, as in a secure private conversation unless you have the keys on your device.
