Aye, all cell-phones have wiretaps, and I'm aware of blatant targeted advertising by Amazon using auditory data from similar devices. Still, it may be possible to reduce manipulation by limiting inputs for those which are incapable of removing their wiretap, or whose family and friends will not write to them using XMPP+PGP or what have you. I'm not sure if OP is looking for something practical for their situation or what their situation exactly is.
