I know that a lot of content on the web is rehashed itself, but many creators actually review products themselves, speak from first hard experience, research, etc.

The original knowledge has to come from someone human.

How can Google promote its "1 trillion facts" database of scrapped content and just use it to show answers to searchers alongside ads.

Seems like they are doing this without regard for much anything else because OpenAI is a new entrant and about to threaten their search empire?
