Your phone, your choice.
Until you try to install a real firewall or adblocker*. Or until you try to uninstall all the crap that comes with the phone. Or, you know, try to block all those useless services every application must run. Then you realize it's not your phone as you can't get root access.
A phone paid by you and owned, partially, by Google, your provider and the manufacturer.
*real as in not using a VPN. Think AFWall+ and AdAway
