>Plenty of companies are quite transparent about their data collection practices (set up an Apple device recently?)

I have not, not recently, but what you say is simply bullshit. They're "transparent" in that they give you a ToS loaded with legalese that they know you couldn't easily read through to find just how much and where they're squeezing your life for information to store. In cases where they simplify this with some less legalistic declarations of data use, what you often see there are numerous weasel words and phrases to very ambiguously describe what's being done. You know, things like "We MAY collect some information for the sake of improving user experience" and blah blah....

Then of course, there's the outright lying, which also happens, in which big tech companies simply fail to mention some types of data collection anywhere (the Amazon Alexa voice recordings being listened to by humans is a good example iof this)

This isn’t buried in a tos or legalese

Apple prompts you for each piece of data collection during the setup of an iOS device (and lets you choose if you want to share).

You're presenting the shining example in the corporate world of responsibility with customer data, Apple, with every other company and saying that everyone does it this way?

Most companies hide it in legalese. Some companies claim they're not sending any data and then send it anyway. Looking at you Philips Hue lights.

> You think companies should loudly advertise something people don’t care about?

It's not what I said.

> why don't they loudly advertise the data collection

This I wrote. I didn't write "companies should loudly advertise something people don’t care about" -> you added something to my sentence, taking it out of context.

I wrote my opinion already, but I'll repeat it anyway in case it was not clear. I think you can't know if people care about it or not, as long as they're not informed about it.
