I have friends who work at google who go to great lengths to tell me how seriously they are made to take privacy and the efforts they made (even before GDPR) to be sensible with the data they have access to.
I have friends who work for the government, civil service et al who are unable to be as vociferous or insistent with any reassurances they feel able to offer.
Draw your own conculsions.
edit it's not to say I am comfortable with google, amazon et al and the amounts of data they are accruing. But just because one dog might have bitten me does not mean I will present my butt to another one to take a larger bite - particularly when that dog seems to be displaying distinct signs of what might be rabies or the like.
