Google and meta (et al) receive money in exchange for the info of their user base. That they're playing 3 card monte (shell game?) with the data to "hide PII" - which has been mathematically proven to be impossible (currently, perhaps forever) seems a hair not worth splitting, considering their market caps.
Put simply, if there wasn't a financial reason to do the data collection google would simply not do it. You don't get rich shareholders by writing a lot of checks to seagate.
