Why not both? Why not collect all the information you possibly can, whether or not you immediately see obvious value to it, and then find ways to justify it later?

Because it's non-trivial and it costs a lot of money to do that, in terms of engineers' salaries, storage, etc.
Well-run companies don't waste money just because they are flush with cash -- especially not when that cash represents board members who want their investment to pay off, not be frittered away on something with no business value.
I'm not claiming that they don't collect as much data as possible including data with no immediate use. Perhaps they do. I don't know. I'm claiming that this instance does not appear to demonstrate them doing so.
