And Google does *exactly* the same thing; or are you saying Google asked permission of website owners before they copy website pages, extract data from them, and then build indexes they keep in their database?

One more time- why is it wrong when Ancestry uses that process but isn't wrong when Google uses it?

Forget the motives, forget the money- stick to the actual question.
