Once you send something the person at the other end is in control of what happens to it.
True, but this is the beauty of trust. I decide to communicate one way or another with someone depending on the level of trust. Them deciding to break that trust is a risk I chose to take. However, I do not choose to communicate with Microsoft, whatsoever. Windows Recall is the most blatant piece of spyware ever; beyond comprehension how this is so normalized.
I'm afraid this comment shows a severe underestimation of the gravity of the issue. Windows recall doesn't stop at borders even if it were illegal there.
