Good example, thanks. SEO spam like this is indeed a problem. Perhaps the underlying issue is that GSearch was originally designed to "find webpages," not "answer questions." (I'd expect that high-quality, official webpages exist for queries like "Nest Thermostat G4CVZ operating manual" or "HVAC enthusiast forum." But that's not the case for a question like yours, and SEO spammers have fooled Google to become the best result.)
