You'll also have to ask what's the difference between Google Drive (or any other online file store) and IA here though. I've found plenty of complete copyright works on Google Drive.

Do IA respond to removal requests? Did IA staff upload that film?

For that, Google Books took works still in copyright and made copies for commercial purposes, they somehow were allowed.

The difference with Kim Dotcom is possibly that he sold (!) more movies through his activities.
