You don't expect your health data, financial data and purchase history (does that include anything paid for by Apple pay?) to be shared with Meta just because you are trying out Threads.
What I'd be interested in is, if [Evil Company] (not necessarily Apple or Google or whomever) got a hold of all the data that was vacuumed up in the process... how is that going to translate into them being able to do disturbing things?
I'm not saying they can't or won't... they record and store this firehose of arbitrary data in arbitrary formats... how they make sense of it. It's not like when you open Threads, it goes "ooh there's pictures of his dog... INSERT INTO Dog SELECT 12345, 'great-dane', {base64}"... They collect all this data... But it's not well formatted or understood.
Don't get me wrong, there's an ocean of money for whomever figures out the most evil stuff to do. I'm simply curious how.
I don't do any finance with Google or Microsoft, I def don't give any health info to Microsoft, I use degoogled browsers, so I don't think they are able to grab any URLs/searches(or if they do, its clear they arent current matching anything to my main account).
Every company gets a little bit of information, where as, I'm suggesting that in this particular case, 1 company gets everything.
But in terms of using those platforms - you likely log into your bank via a chrome-based browser or Edge.
Even if not, you are still running a browser on their platform. Why not scrape financial information from another source such as disk storage or by monitoring network/crypto API?
If the platform vendor turns malicious, why presuppose they will only alter the behavior with respect to their own apps?
Indeed, and you aren't consenting to Apple sharing such data by installing/using Threads.
The privacy label he showed is something Apple requires apps to do to indicate what data they may collect and what they share. Meta has basically decided that people can type in anything in a text box, the servers save the posts, other people view the posts, so every checkbox has to be checked.
