Gmail security (or ANY google service) has been in the news for years. Why is everyone so paranoid? It's not like they are looking for random Android user from 'between California and Asia'...they are looking for serious people doing serious ****. So unless you are selling 12-packs of nukes for $14M, I think you are ok.
I also love how they list the file 'EPST.apk' as a 'spy' program...EPST is the .apk that runs your carrier programming. Your phone MUST have this file to operate unless rooted...in which case, if you are rooted...why are you worried?
PS-for those not in the 'android know'...there is a one click rooting app in the market and CyanogenMod builds a ROM for just about any phone worth owning...so root, flash CM7 and enjoy the privacy you are so concerned about.
