We care quite a bit about search quality. We've made a bunch of changes over the past year to address some concerns that have been raised our Perspective feature which is part of that recent rolled out on mobile https://twitter.com/searchliaison/status/1673382545730457605 and we have further ranking changes coming soon, as we described here https://blog.google/products/search/google-search-perspectiv...

I tried the example you cited. The "blurb" is called a snippet; the snippet comes from the web page itself. One of the pages had that actual text, which is why it appeared. Why it had it on a page that's primarily about coaxial cable isn't clear, but we'll look into how to improve.

As for sending feedback, each link in the results has a little three dot icon next to it that brings up our "About This Results" panel, and you can send feedback that way.

Also, to belatedly introduce myself, I'm the public liaison for search at Google. It's a position we have within the actual search engineering team to help us gather feedback to improve search quality. Feel free for you or anyone comfortable sharing examples of unhelpful results to flag me about it:
