I want and expected it to listen to everything. Sure it can be used to harm me but it won't be a good business decision, on the other hand they can use the data improve the product and service for me.
In the advertising industry harming you is often a great business decision. Dissatisfaction breeds demand.
I've found a lot of improvement in my life satisfaction (and the size of my savings account) since getting rid of ads almost entirely. I've also found that I never feel the need to be in a hurry to buy something. Buying seems to be a slower process -- whenever I want the thing and feel good about it, not just because it's hot right now or I'll miss a deal. I know there will be another.
This may not apply to everyone but it was my experience. Clearly not a big fan of the ad industry haha.
