I would rank that pretty low on my list of things to worry about a search engine doing. Actually, to me, that would be relatively fair in terms of monetization of a search engine product.

I would turn the feature on if asked by a reputable and well-meaning company. Especially in the case of a search engine seeing as they are providing the link afterall.

Search engines rely on trust. Dark patterns that include shady things like exploitative URL insertions on clicking links are highly relevant.
