How is simple analytics or A/B testing that's NOT internet-wide tracking (that is, only for the website you're on) or sold (which would be outright illegal without explicit consent) hurting you? Genuine question, because I don't see it. Internet-wide tracking across many sites: sure. But that's a very different thing – it's the difference between "I'm home Darling, I saw Sander at the mall today" vs. "Hello everyone, here is everything Sander did this week".
And before people would nitpick my comment, metadata is surveillance. https://www.schneier.com/blog/archives/2013/09/metadata_equa...
If I passed by your house and saw you walking your dog at 10:34 18/05/2023 and then promptly forgot about it, it is not a surveillance. If I set up a permanent observation post across the road from your door and will tail you daily everywhere you go - it's a surveillance. Even if I pinky promise that it is my own internal information and I would not share it, sell it, exchange it etc.
But I don't really see how that is happening here? I agree that would be bad, but merely checking "a user visited my website" is a very thing than seeing what someone does all over the interwebz. It's very questionable this minimum of information can even be tracked to you when done right.
And how do you even get someone's mail address without an extensive internet-wide profile (which, again, isn't what the premise of my question was in the first place)?
How is that hurting you? How is your every movement being tracked by a single agency such an issue? They said they would keep it private, pinky promise.
An extreme case is on the other side, is to compare simple site limited tracking to a coffee shop being able to see who enters the door. Why should they track how I look and the way I'm dressed? Does it make service harder if you have to work blindfolded? Though luck, my privacy is more important than your wish to provide your customers with good service.
In your example they are only looking. It would be different if they were recording their observations in a structured manner (aka cameras). Even writing it down by hand would raise flags, would it not? Sure, being a human means looking at me and my coffee to brew it, but recording everything I do in (semi)permanent storage? Is that human? Is that necessary to brew coffee?
