Why the Internet is freaking out about the new Google privacy policy

What are they changing about the new Google privacy policy?
At its core, the main change is that instead of having several privacy policies formultiple products Google will just have one policy governing all of its products.
What does this mean in practice?
Firstly, the privacy policy is far more simple than the polices that came before, since users only have to sign one thing instead of many things. It also makes it much easier for Google to track a user’s data between its different tools. For example, it could use what you do in your Gmail to refine your search results.
