(I'm not making a claim either way on whether or not in this case it's true that devices are spying on us, just that this line or thinking is absurd that it doesn't really matter if a given thing is true)
Fast forward to 2013 and Snowden.
Our defaults for "they wouldn't do that" when it comes to your privacy are all wrong.
If that's a "conspiracy theory" that you need to dismiss so that you can go about your life, fine. But the truth is, these people are constantly up to no good and you can't trust closed software nor hardware. The technical capability for draconian mass surveillance exists.
Kind if like, 'I cant believe it's come to this, but given all the evidence, it's justified."
At the same time we see the incentives, and the incentives are to collect and analyze things.
A device which does not have a hardware cutoff switch, which you've allowed to listen for it's own prompts ("Hey Siri, etc") can listen to you. So far we're all speaking "current knowns". Nothing about that is conspiracy.
The trust part is "storage of data received" and "use of that data". Sure it probably does not today - but will the terms of service change tomorrow?
An example parallel are Alexa devices listening, and accidentally storing whole convos.
Devices do listen to all sounds to listen for their "prompt" - how do I know what is actually discarded? And with precedence, I don't think it is 'crazy'.

Just as if my location/microphone were able to be physically turned off on my phone I would not have to trust that someone isn't always listening in on me. If I can't do that it is not unreasonable not to trust it. There have been plenty of instances of these things being abused.
Insurance companies analyze purchase records for modeling lifestyle risk.... if I were discussing a family member who had a health scare how do I know that info isn't 'surfaced' to insurers, etc?
