Again with the unfounded statement. Where are you giving away personal info? You register the device with an email, what personal info do you think they're collecting? Do you think they can identify you because you named a speaker "living room"??
They now have my email. There are these things called "relational databases" that allow one to collate lots of other data with a unique identifier. There are organizations that do nothing but gather that data and resell it. I do my best to stay out of that marketplace.
What benefit is there to me to provide any seller of consumer goods with my personal data?
Why is the end user supposed to give a shit about a company's missed opportunities?
