It was uncanny and creepy, pretended to be a conscious being, frequently lied, and led directly to that guy who claimed it had personhood... I can completely understand why Google chose to keep a lid on this kind of thing, hoping to be able to clean it up and produce something that could be reliably used for a product instead of a novelty. That's back when Google was still sort-of pretending to have ethics (though they didn't)
OpenAI beat them to the public presentation of this stuff because they didn't care.
