Valuable for blackmail, but not really useful for anything else; the commercial value of information rapidly degrades over time. Knowing I want to buy a new fridge today is very valuable, knowing I wanted to buy one last month is nearly worthless.
That depends on what they can get out of the data, besides the obvious. I'm thinking of the story about Target knowing that a girl was pregnant before even her father did[1]. Even longer trends can probably be derived, regarding personality traits, income, etc. That information is worth a lot even months or years after it was captured.
