Well, they had an internal ethics team that told them that their technology was garbage. That can't help. The other guys' ethics teams are all like "Our stuff is too awesome for people to use. No one should have this kind of unbridled power. We must muzzle the beast before a tourist rides him" and Google's ethics team was like "our shit sucks lol this is just a Markov chain parrot doesn't do shit it's garbage".
The unfortunate truth when you're on the cusp of a new technology: it isn't good yet. Keeping a team of guys around whose sole job it is to tell you your stuff sucks is probably not aligned with producing good stuff.
There's almost like an "uncanny valley" type situation with good products. As in new technologies start out promising, but less okay. Then as they get better they becomes close to being a "good project" the more it's not there yet. In that way it could feel sort of worse than a mediocre project. Until it's done.
There's a world of difference between saying "our stuff sucks" vs "here are the specific ways our stuff isn't ready for launch". The former is just whining, the latter is what a good PM does.
