Which raises a very interesting legal question: If the data is recompiled, despite having come from another source via an intermediary (who are using that data to describe the products they are selling), is it still subject to the database rights?

How about we try out a reductio ad absurdam: I'm going to start a startup. Our business model is to license the information on customers' websites, and then license it back to them in turn. This then means that anyone who uses our services in the UK can sue for copyright on lists of facts obtained by screen scrapers, as they've been through our database copyright washer. Think flight prices, hotels, cars, anything.

Is that a viable business model? If not, why not?
