It's not "whatever reason". Google is in the content selling business now - which means they are going to add as much DRM and restrictions to their operating systems, browsers, and devices as possible, to either try to "protect it" (which I think we all know it never works), or to please their content suppliers.

This is not just a constant thing we're seeing either. Expect Google to become ever more restrictive and anti-piracy, as they delve deeper into the content selling business. The days of the "Open Google" are long gone now, and they're never coming back.
