I am just guessing but it sounds like maybe they broke their global filters. I've seen folks on here saying they are seeing this behavior on gmail as well. I have not seen any evidence pointing to what the overall agenda would be if this is the case beyond pushing people off the free email services. The conspiratorial side of me could imagine a memo amongst a circle of some business leaders pushing people to mail providers that have money trails. Or perhaps a more benign reason could be these companies are no longer making enough money on their whitelists or not making enough money from tracking email behavior and are silently dropping support of the free services.
