Try searching "how valve index works" or "how valve index controllers work". My interpretation of "how it works" is "technical information on how an item operates". Google will interpret this instead as "how well it performs its intended functions" and flood me with both links to purchase the Valve Index as well as endless reviews. Results on Google are not tailored toward retrieval of factual information anymore. They're tailored to ordinary, garden-variety consumers, and obviously designed to sell you a Valve Index.
To this day I still have not found really good information on how the controllers in the Valve Index actually work. All I get are pushes and nudges into getting me to buy something.
