What's scary is Google can get each and every detail about us, heck they even know where our/parent's/ home/workplace is and can have access to camera and mic anytime. 3/4th of the people are not bothered about any of this and give access without any worries.
I think most people either do not know or decide to ignore because of convenience. We quickly give away fundamental rights that some of ancestors fought their lives to obtain. That's why we need to start with an awareness campaign. We are a small part of that.
