Essentially I see two competing processes here.

Google still has powerful boolean operators. If you use those with intentionality, and pick the hidden 'verbatim' option, you'll have a decent chance of finding what you need. However, these are all vestigial features that a minority of users employ.

The vast, vast majority of users are funneled into product choices. In a way, it helps to see that as the core function, and everything else as a secondary funnel towards that primary funnel. The search engine is designed to work so that people use it, but the end goal is for ads/SEO to be effective for the great mass of users that are particularly vulnerable to them. The GP was looking for price differences, which is something many websites base their business off of, but that's still a tiny portion of the whole and not something Google needs to optimize for compared to the misleading but lucrative results the GP had to sift through.
