If I was using an AI that was designed to answer some class of questions (with independently-verifiable answers) truthfully, and I noticed it responding to questions of that class with demonstrable falsehoods, I would at the very least file a strongly-worded bug report, triple-check whatever work I'd previously done involving answers it provided, and cease using it in the future. I don't think such a response would be exceptional in it's decisiveness; other users would likely go further, seek out venues to complain openly. Consider the uproar over Gmail's 'new look.'
