<Large tech company> knows Everything about you and the threat of having all that information looming over peoples head ought to cause fear. If the data is leaked and mined, lives are harmed and sometimes irreparably. Clearly there is evidence of damages and I think a lawsuit makes sense. If you poison the air with mercury causing a significant chance of fetal brain damage, you get sued. Why should you not be sued if you leak information that leads to suicide, divorce, etc...?
