I feel like the lines between a data leak and large scale scraping are getting blurred. At least in their impact for the user. Which is a bad thing as it will support the "so what" attitude that many people have toward their data.

It is a fact that all this data is already being crawled by bot nets.

If all data is leaked at once, this is similar to a large scale successful crawling of the site. At least from a user perspective.

So I get what you are saying. It sounds more dramatic than it actually is. It is still a massive leak. But from a pool that scummy businesses have been thoroughly scooping from already anyway.
