This is a beautiful quote because it is an example of one industry's bad behavior leading to another industry's bad behavior, upon which the first industry then users the second's similarity to justify themselves. Cars only started doing this because phones made it normal. It's wrong in both cases.
It's similar to when Apple defended it's 30% store cut by claiming it's an "industry standard"... specifically, an industry standard that Apple established.
How do you define personal information? Let's use Chrome as an example. Recording what website I visit is clearly personal information. What about recording how many tabs I have open, how much RAM each tab is using, and when each tab was last viewed? Is that personal information to you? I personally don't value keeping that private and it is probably a valuable piece of information that could help the developers improve what has been one of the biggest user complaints about Chrome since almost its release.
I think that is generally OP's point. Each piece of data exists on a spectrum in value for both the user and the developer. Data should be kept private when it has value to the user. There is little harm in sharing the data with the developer when the user would deem it low value and the developer would deem it high value.
