why doesn’t the rf shut off when the door is opened? And a second one: why was it deemed worthy of publishing an article that a microwave oven interfered with data collection since 1988?

It does, but probably not instantly. Just guessing, but ... A magnetron is a thermal diode that can continue to generate RF as long as there's enough emission, and enough voltage to move electrons past its cavity resonators. The door uses a choke joint to prevent RF from escaping, and as that's being opened, it can radiate. And it's newsworthy because people smart enough to run a radio telescope should be smart enough to run down something like this. IMO!
