I probably could type all night.
Edit: under "do you have foreign accounts" check "no" as well. (Actually don't do any of this you will end up in federal prison)
I suspect Google collects and keeps personally identifiable information in ways that are illegal in EU too. And of course YouTube directly created and profited from copyright infringement.
And the internet industry as a whole has very effectively sabotaged the EU "cookie law", by implementing it in a way that annoys everyone and benefits nobody, pointing the blame at politicians while making big profits from privacy invasions of unsuspecting people.
