Not sure if I understand you here.
Google, for all the negative press and bashing they are getting lately, has not hidden what they collect, how they collect. They also do not sell user data (that's not their business model). Sure, they have had their share of issues, but I don't think they are systematic or intentional. They are happy if you want to take your data and go to someone else - they released takeaway tool more than 10 years ago.
Fb, on the other hand, never were trustworthy, even before any of the recent scandals became public. They have had history of changing things around that led to users unknowingly expose their details they thought they had locked down, more than once. They have been caught lying to advertisers about clicks and views.
But those finer points are lost when they have successfully dragged Google in the mudbath with their smear campaign, irrespective of the scale or intentions at Google.
