I generally agree with the statements here but the example of the baby thermometers seems to be a false equivalence since there is no variation of pricing of the products but instead it's a personalized search results page that takes into account what they think this person might want. It actually would seem silly that a newborn parent would NOT want a baby thermometer and it just so happens that baby thermometers tend to be pricier. I know the stance from the EFF is likely that everyone should see the same search results and only allow a direct ly expressed query to influence the sorting/ranking.
