Google will rat you out to the Feds for only $25 and Yahoo! will for $29.
Google receives "tens of thousands" of requests each year from the government to turn over user data, and it complies any it deems legitimate. But the information comes at a cost: 25 bucks per head.
According to documents obtained by privacy researcher Christopher Soghoian under the Freedom of Information Act, Google charges the Feds $25 per account for surveillance services. (No word on if Google displays targeted ads alongside the data it turns over.) Yahoo charges $29, while Microsoft lets government spooks spy on their users for free. Most domestic wiretapping requests come from the DEA, so it's best not to do your drug-dealing via Gmail.
