If Google isn't engaging in discrimination then they have no reason not to release the info to the government.
Maybe it isn't technically illegal for Google to withhold this info.
If so, they would be free to not release it.
And us not idiot engineers and the media would be free to use this as evidence that Google must obviously be discriminating.
The court of public opinion has different standards than the court of law.
Don't like it? Think you're innocent? Then release the info and prove it! I see no reason to give large for profit companies the benefit of the doubt.
