I didn't think one needed permission to change freqs (or anything else for
that matter) while receiving flight following.

2. When receiving VFR radar advisory service, pilots should monitor
the assigned frequency at all times. This is to preclude controllers'
concern for radio failure or emergency assistance to aircraft under
the controller's jurisdiction. VFR radar advisory service does not
include vectors away from conflicting traffic unless requested by the
pilot. When advisory service is no longer desired, advise the
controller before changing frequencies and then change your
transponder code to 1200, if applicable. Pilots should also inform the
controller when changing VFR cruising altitude. Except in programs
where radar service is automatically terminated, the controller will
advise the aircraft when radar is terminated.
