On Google's transparency, I think you need to bear in mind that, even if they have stopped now, Google was built by routinely collecting unseemly piles of data about each of us on the mostly correct assumption that our Overton windows precluded consideration of such invasions. In the meantime, law enforcement has helped itself to the spoils through geofence warrants that can earn you police scrutiny in, again, post-hoc happenstance that would be disruptive and jarring to one's life. On you last point, consider that some people view those features as marginally useful or view abstinence from their use as worthwhile self-deprivation (e.g. I spend no time alone, so my emergency calls are already a solved problem.) Having said that, I don't use a Graphene OS Pixel or any other de-Googled phone, but the existence of such a market shouldn't be surprising.
