I feel like you are operating under the assumption that deleting this leaked data is trivial, that they just have to hit a delete button and the data is gone.

This is not the case; it is not obvious, trivial, or easy to delete the leaked data. It is not simple to find it all. This is not like they are being given a URL and being asked to clear the cached version of it; they are being asked to search through millions of pages for possibly leaked content.
