Let's be clear, the reason Google didn't want to jump into conversation search is because it invalidates large portions of their business model.

At best they want to avoid bad publicity of their tech just being bad enough to throw out racist remarks. But the company who dropped "don't be evil" from their mission statement, and who fired AI ethics researchers for their research in AI bias that Google did not like is not a morale authority on the matter.

Also, Google does not provide an ad-free paid version of google, you statement is a non-sequitur.
