"...I wouldn't consider buying anything in the future, because..."

Did you miss it? You can just say "...because surveillance". [1] :P

I often wonder about half the things running on my phone and since removing some might make it useless I leave it be (not my domain so probably simplified a lot).

I really fail to see how listening in all the time is for convenience though. If that 'feature' was disabled the device would still be just as convenient.
