Originally it was because suggested results were a waste of time and I had used linux in grad school. I liked being able to use my computer how I wanted. As I learned more and more the ethics became a strong enough motivator I got rid of gmail and stopped using google maps. I’m 100% degoogled now, and I never looked back. Sometimes I have friends or people at work who want to collaborate using google products. I tell them I take an ethical stance against it. I will never go back.
