I've tried to raise this, specifically about UK government websites before. The gov.uk people didn't want to know, and told me it was OK - google promised to anonymise the data they were collecting.
And we should just trust this, that google are given all the data they need to track everything that UK citizens do to interact with their government online, but they won't.
1. persoanlly i'd rather trust goog than any government out there. at least with goog i know where i stand, and i know what it takes for them to change course.
with governments there's no recourse except for voting every 4ish years.
2. if you've got ublock or some other tech installed then you can easily ignore your own advice.
