i would much rather have a device that i can actually control and trust instead of having to spy on a device that's most likely spying on me in ways i might not like.
And what's great is that your personal preference on these things takes absolutely nothing away from the device itself.
I don't think i'll buy one because I have Siri in my pocket at all times, but these privacy concerns aren't absolute truths. They only matter to you because you're sensitive to it.
