I have a blackberry hooked up to Google Voice and Mail servers. They know my name, address, all my phone numbers, all my emails, my contact lists, frequency I receive calls on my Google number, text transcription of voicemails. They also can potentially record every call I receive and make with GV.
Considering the benefit I get from just Mail and GV, the datamining is a cost I'm willing to make. I also know if my phone is lost, I dont lose my data. And I can back it up elsewhere.
And I am somewhat happily shocked that they came such forthright that they "fired him for snooping". Most places will only say "They no longer work for the company".
If you're on the internet, your information will always be available to someone. On the internets, as in real life, this power can be abused.
Appreciate the fact that they're open about it.
