the lack of control group undergoing the same monitoring means there is a high chance of bias.
I would also want to see secondary measures such as the amount of queries people did and what they actually used it for. Might be worth tracking over time to see if there is an increase or decrease in use. These sort of secondary measures give some confidence that it is useful and its continuing to be so and its not just people behave differently when watched.
There is no end to the greed of those with millions and especially billions and they aren’t content to just keep running a profitable business, they have to get all the money.
This is just the history of humanity and finances forever, the one saving grace in all this is every big business gets complacent in its money making and seeks ever increasing profit (and becomes management heavy) until a young upstart finds a way to do it a lot better and cheaper and disrupts the market. Google has become the big lumbering unable to change organisation seeking maximum profit now, its become IBM.
