A notification popped up on my phone today talking about this. I hit the button to adjust the settings and found that it was opt-out.
No, I don't want my app usage being used for ads. I don't want targeted advertising at all, but none of our fucking countries will take a stand against this shit.
This might be the thing that finally pushes me to switch to GraphineOS.
There was a time that I felt like Google was one of the good guys; they seemed to be doing great things with their products and pushing Linux. Now I feel like I want to de-Google my life.
Google keeps a log of every app opened and for how long.
Is how long what they mean with "how you use them"? Because otherwise it sounds a lot creepier than that.
