Weak Signal's description 
In a keynote Google’s former CIO Douglas Merrill describes Google’s approach concerning internal innovation culture as offering employees as much freedom as possible in their working/innovation processes, e.g, by letting them choose any operation system, any location and any software they want to use. This increases the company’s rate of return. Any other way would just stifle their productivity in innovation. This has an effect on Google’s security policies: Google tries to close the upcoming security-gap in its own infrastructure e.g. by securing their servers rather than opting for the traditional solution, which would be to secure each device, which is used by an employee (and thereby restricting the devices, which can be used: software, computer, browser, etc.).
