It's like reading that BP disbands their team for renewable energy innovation. Am I supposed to be sad? I'm not. I don't care. It was all fake from the very beginning even if the team had many people who were naive enough to think otherwise.
The point of such teams is not to improve ethics. The point is to have enough credibility to affect the discussion. (E.g. observe how much "research" in AI ethics has financial ties to large companies that are heavily invested in AI-based products at the time.)
What a properly ethical corporation would do is openly admit conflicts of interests and listen to external feedback.
