The only exception to this is google maps. There isn’t really an alternative, because they have the network effect going with all the points of interest added already, and crowd sourced by people, plus the reviews of business and restaurants. Even if you can get all that going with a Foss app, its not going to be tracking you, and unfortunately maps is the 1 reason for tracking people that actually gives the user some benefit, traffic data. I don’t think there any other Foss maps that gives traffic data, which if you live near a city or travel a lot, its invaluable.
I stopped buying their phones when they started locking the bootloaders for the Qualcomm ones in the US. My last one was a galaxy s5. Sadly now I go with the pixel line directly from google, because I know it’ll be unlocked.
