NPR quits Twitter after being falsely labeled as ‘state-affiliated media’

Your data has monetary value to google. Giving them access, without getting any money from them (or even knowing what ways it will be used) is not something you must do.

To be fair, while you may not be getting money in its direct form (cash, bank deposit, etc) from Google, they are providing you a service which costs them money for free. So they are providing something of monetary value.

Only the individual can determine if their data is worth that free (to the individual, not free to Google) service. I’m assuming that most people in a privacy community would be against that, though.
