Am I the only one who finds it concerning that they capture like everything ("Data entered by customers in using the products" and "Clickstream data capturing usage of the product") and persisting it just for the sake of having it and finding a use for it later? Also they collect data directly from 100s of relational databases, that sounds like a terrible idea to make your DB schema an API for data collection.

I am pretty sure this has been a standard practice for at least a decade now. Isn't that what the "big data" meme is about? Store everything, because you can always get more computational power and statistical techniques to extract value from it later on.

And also you sometimes don't have capacity to do all the analyses you want at the start. Throw all the computational power you want at it, but if you don't have enough humans down stream to make decisions from it, then storing that data for later use makes a lot of sense.
