That would have been better as you say, but they did it when they decided what to do. Of course most people could not read the message, but the only alternative would have been to delay the new training or just leave everything the same and get all of us very angry.
Changing the training is a bad idea when something goes wrong with it.
I remember that when training was delayed for very long some time ago, some users did not notice it and changed their trainings. It is the same thing now.
