Windows Recall wont just be a privacy issue for Windows users! Even if you’re on Linux or a Mac, every interaction you have with a Windows user will be saved by that person’s Recall. Recall will become a desirable target for malware, as attackers will get access to everything on that system, and EVERYTHING that user has ever seen.
I’m strongly suggesting folks consider contacting elected officials and regulators. We need to encourage companies to do a better job of protecting our data.
