I have no idea if their app collects this information too, but it's just a matter of time before someone becomes interested to it as it happens with any kind of data that can be used to profile people.
A person who listens to music at unusually loud levels SHOULD be charged more for insurance. Just as a 24 year old Asian single male software engineer in Mountain View gets charged more for car insurance. And if you have poor hearing skills, I sure as hell don't want you on my Marvel Studios audio engineering team (example)
It seems that your really want everyone to be treated equally when in reality it will never happen, and in fact comments like yours increase the disparity.
No one who I know personally, outside one or two folks who also work in tech and would fit perfectly with HN's demographic, cares about tech spying on them.
Friends of mine have gotten home assistants, video game console, smart TVs, etc for years without one thought of their data being sold to a third party.
And it is one reason why we are hurtling inexorably to Idiocracy...
Considering that code has creation and maintenance costs, I doubt this would ever actually reduce the price. They would just inflate the final price to cover the cost. And if it collects enough data to actually make money, the price reduction would probably not significant enough to match perpetual data theft. Not to say that some people wouldn't go for it. It's amazing the lengths people will go to for free or cheap products.
But there's still the many liabilities of collecting, transferring and securing sensitive data. People who know the risks and hassles involved with identity theft would be very selective about these services.
Of course it would. What is the consumer benefit derived from the collection of this data?
