What Jamie wrote
Apple deserves some criticism here and I hope they take the same privacy focus they have brought to Safari and extend it to Mail. I love the my Pi-hole protects me no matter what platform or app I’m on. But I would love to see user visible notifications of surveillance in email.
By the way, I do not have any tracking in the Weekly Thing. None.
