If one chats/mails with a person using Windows, despite using secure private protocols, every message will be stored by Microsoft’s Windoze Recall. Either I’m missing something but this feature seems like the most grotesque breach in online privacy/security.
What are ways to avoid this except for using obfuscated text?
If there’s anything sensitive I’m communicating with someone digitally, I make sure that the person in question has basic tech security skills and knowledge about privacy, including telling them to stop using Windows. Including taking the time to teach them basic stuff (like full disk encryption, VPN and Tor usage, explaining E2EE, etc) myself. If you have a high threat model but are talking to non-techy people, you should be taking the time out of your day to do this.
If you’re thinking “wow I can’t be bothered to do all that”, your messaging is probably not sensitive enough for this to be a significant concern. Not that “if you have nothing to hide you have nothing to fear”, but just “the amount of time you put into security and privacy should be proportionate to your threat model and the cost of compromise”.
