rare scotus W, but i strongly suspect that because this data is "owned" by someone other than the people that generated it that said owners will simply choose to voluntarily cooperate with government inquiries 100% of the time. You can suppress information if the government unconstitutionally compels google to turn it over, but I don't believe that you as a defendant could push to exclude evidence if it was willingly turned over by a third party that had the right to have it.
