I think Stallman raises some interesting and valid points (in his article in the guardian. It is worth reading it to the end). For example this:
"On most Android phones, this firmware has so much control that it could turn the product into a listening device. On some, it controls the microphone. On some, it can take full control of the main computer, through shared memory, and can thus override or replace whatever free software you have installed. With some models it is possible to exercise remote control of this firmware, and thus of the phone's computer, through the phone radio network."
I think we need phones with free and open source GSM/UMTS aka Baseband stacks.
