Yeah, we know what happened and it's not that Apple was actively triggering Siri without prompting as a way to spy on people.
The whistleblower you mention (and the article you link) raised that Apple was using human canvassers specifically to filter out accidental activations, or at least to grade the quality of the outcome.
The concern was raised because they were hearing a lot of sensitive information and felt the reporting on it wasn't thorough enough.
Which is certainly bad. It's a problem.
But as the OG's piece says, it is very much NOT an admission that Apple is actively triggering indiscriminate recordings. If anything, it's the opposite.
That's the thing about these. They don't need to be used nefariously to capture all of this crap. It's still a microphone reacting to voice commands. On billions of pockets. Any amount of false positives is going to generate thousands, millions of random recordings. I have random recordings of myself from butt dialing my cam app or a voice memo app and I have NEVER turned on voice activation for a voice assistant (because it's bad and intrusive and a privacy nightmare).
See, I'm not saying it's OK with me.
I'm saying that Siri working as advertised is a privacy nightmare. People somehow feel the need to make up a fictitious exaggeration of what the issue is to make it feel bad to them, except that's not what's happening and it's entirely unnecessary, because the entirely allowed, EULA'd up, publicly disclosed usage of data canvassing throughout the entire ecosystem is much, much, MUCH worse in aggregate.
What confuses me is why that is ok to you.
