Except now you don't have control over your own device. I don't think they are orthogonal goals. Give me root on my iPhone and I'll switch for the privacy. Leaving gapps off an Android install is becoming crippling.
Why do people actually want to root their phones? What kind of advantage does it give to the general user, who flaunts the fact you can do that on android? What can you do now, increasing the usability of a phone, that you couldn’t without a root? Honest question, because I have absolutely no idea.
Firewalling traffic and tunneling also requires root. I believe it is a popular way to block ads and analytics, either with a hosts file or iptables.
