That is akin to this: “Hey, your house door is unlocked.” “What are you talking about? I left it unlocked on purpose, but it is safe, I wired the metal handle to the power plug, nobody bad can get in.” “What about the good ones?” “I installed a Coordinator™ that calls me when you ring, and I can open the door remotely.” “Wait, didn’t you make this house with the promise that everyone with the key could use it?” “… well, I don’t see you finding a vulnerability!”
