I believe that if you are using my book as data/model/whatever for something that makes money, then I want a piece of the action.
If it's just a paragraph, fine go ahead. But the whole book? Give me money.

If I write a non-fiction kids book about a boy who finds out that he is a wizard and goes to a secret wizard school, I don't owe JK any copyright money.
If I read your books and use them as a strong foundation from which to write stories (e.g. I don't do any worldbuilding, & just re-use settings/characters without my own introduction), it seems reasonable that my derivative would need some kind of license from you.
If I read your books and write book reviews about them (including small excerpts from the book), it seems unreasonable to require your explicit permission.
I think the website mentioned (which displays stats about a book, and a couple of excerpts) falls far closer to the latter case than the former case.
and even if you could get money for that, it would not be much. if the tool analyses a million books, and then the service makes one million in revenue, no more than $1 of revenue can be attributed to your book. and only a fraction of that would go to the book author because most of the revenue goes into developing and maintaining the tool. so you'd get 10c. you would make more money by spending your time writing actual prose that can be sold, instead of complaining about this particular tool.
