I still don’t think companies serve you ads based on spying through your microphone

People always talk about getting served ads after they talk about something. I think it's the other way around. The ads put the thought into your brain and then you start talking about it and notice after you've already been thinking about it for a while.

In September, I was using reddit, had an iPhone, etc. I was generally aware of digital privacy, probably moreso than the average person, but by no means was I knowledgeable.
I was running a beta on my iPhone at the time, for context. I had a short conversation with my roommate while my phone was in my pocket. I took it out to text my partner and pressed the dictation button. My phone proceeded to type out the majority of the conversation I had had maybe five minutes earlier with my roommate. Literally ruined my ignorance is bliss and now I have a Pixel with grapheneos and use almost exclusively open source software with a major focus on privacy. Obviously this is an anecdote from some idiot online and I can't verify what I'm saying at all, but the experience definitely shook me.
On Android, I have the mic, location, and camera blocked via the pulldown tiles menu. I turn them on when needed. The OS and some apps like to bitch about this sometimes but it seems to be working ok.
My iphone does not offer these blanket blocking options. It's a work phone, so I just leave it off unless I need it.
So one of the devices allegedly grabbing keywords from heard conversations, you'd trust with a software based toggle?
I'd only trust hardware toggle.

Using your search data is bad enough
It's well possible and previously tv mic had been used as bugging device. The problem is, way too many security researchers look in system level software of iOS and even other components of the device that such practice will be too risky for apple (same applies for mainstream android products). Also processing realtime audio, finding potentially unrealiable topic from it and doing realtime ad is actually too much work as of today's tech (might change sooner than you think though).
What, I think, is more practical is to use the whole query after the wake word to show ad, and potentially use other app tracking data, which is way much reliable than voice for targeting purpose. Voice data is useful for bugging purpose, primarily (ab)used by nation states and LE.
I bet in the medical procedure case mentioned in the blog the user searched/talked about that in other apps and average people aren't good to notice these privacy leaks.
too much work for today's tech
All the assistants listen all the time for their codeword. The new pixel phone show you a list of songs played around them and more. It is already happening all the time in the background.

I don't either hut the alternative is much worst in my opinion. It would mean the algorithms are so advanced they are predicting conversations instead of listening to them.
