so just to rephrase:
"google should stop collecting data because it might be compelled by law to provide it to the government. the government should compel google to stop collecting that data"
More like Google will be/is compelled 100% by any random state court or not-a-court-but-cops-directly-because-we-decided-warrants-are-for-suckers to provide data (you don't need a warrant for "give me who you think was there" queries -- that is a different wtf). So Federal lawmakers should make it clear that Google (and any Google) should not be doing any of this.
Might as well use the whole branching of the government and make use of the checks and balances for mankind's good and welfare.
And if one needs more convincing I would point them to look at the whole 19th and 20th century history.
