Re: Security risk?
Routing a phone simply re-enables the root/admin function that was removed by the manufacturer/carrier. It is a bit like Dell/HP/Lenovo deciding to disable run-as-administrator on your Windows pc.
A rooted phone user can then use that run-as (called sudo or su) functionality to better manage and secure their phone. Everyday apps don't run as root anymore than word our excel do on your pc.
