I'm aware of at least one community that shares copyrighted videos on Google Drive, and I'm sure there's more. There's at least two ways videos get taken down. 1. If there's too much burst traffic (like when a new popular episode is released), you can see that the video exists but GDrive won't let you stream it in the browser. I can't recall if you can still download the file. There may still exist a workaround where if you copy the file to your own GDrive (and your own quota), that copy will be available to you. In any case, usually the file becomes available again when traffic dies down. 2. Accounts sometimes get removed, or at least their shared files are no longer available publicly. I assume this is from getting too many copyright strikes against them. I would assume if the video was popular, at least #1 would have happened here. It's unclear to me from the article if anything beyond that happened. That said, it wouldn't terribly surprise me if there was some process somewhere that matches up videos banned from Youtube and restricts their availability on GDrive.
