Google has no practical way to address ethics at Google-scale. Their ability to operate at all depends as ever upon outsourcing ethics to machine learning algorithms.
I think it's gotten a ton better vs 10 years ago, and is getting better still.
More on topic -- when folks here complain that Google can't release these models, it's not like they're just sitting there using that as an excuse -- Google has entire teams dedicated to ML safety trying to figure out how to filter out bad stuff, make models fairer, and avoid situations like M$FT's "Tay" (or worse).
