How will Google determine which opinions to protect?

As wonderful as Project Shield sounds, there is a fundamental risk of it being undemocratic.

Why won't it protect all sites regardless of content? Isn't that the point of free speech?

No, Google will decide what will be protected or the people that have the power to control Google in these regards.

Content that will certainly not be protected: - Content that violates the Digital Millennium Copyright Act

- Illegal pornography, snuff videos ...

- sedition,incitement

- confidential NSA stuff (you know, because it helps terrorist )
