The two big differences between private and government surveillance is 1) law 2) quantity. Look at China how the private sector freely hands data over. But ask yourself, is it that hard for your government to obtain that data? Are they trying to access it? The answers are probably no and yes.

If you don't feel comfortable with the government having that data, I wouldn't suggest giving it to private corporations. Even if they are standing up to gov, it means things can change. I think Snowden uses the phrase "turn key tyranny".
