Another factor that isn't being fully accounted for is a new SEO/marketing technique where many people are asking scripted questions publicly on sites like reddit and then stealthily providing answers that market a product or service. This leads to reddit results not being exactly authentic as well. Pretty much most online reviews cannot be trusted as we are begged to do positive reviews of companies (and when companies outright purchase positive reviews, which is also very rampant) also as a factor.

Though Google is at fault for letting their service falter to the "payola" race, many other factors are in play all across the Internet since data quality has faltered almost totally. For major-cost and non-refundable purchases I need to trust, I go to brick and mortar stores and inspect what I am buying. I am thankful not everything has shifted to an online-only model. It's going to be a very bumpy ride on the Internet until Congress and consumer protection laws wake TF up and do their job.
