Yes, but Recall is spyware by design posing as a benign feature. This kind of unethical behaviour I vehemently oppose.

But it doesn’t matter, because everyone else uses Gmail, so any time I communicate with someone, Google reads my emails, despite the fact that I never agreed to their oppressive ToS.

That’s avoidable by PGP encrypting your emails though. But I’m sure you know that, and I’m sure you meant that getting most people to use PGP is a pipe dream.

I couldn’t wait to post this obligatory fragment of Parks and Recreation - Ron vs. Online Privacy: https://youtu.be/8xn1rO1oQmk

It’s more about what Microsoft enforces—spyware—than what other people do.

I’m afraid this comment shows a severe underestimation of the gravity of this issue. Windows recall doesn’t stop at borders even if it were illegal there.

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.
