If you were evil, you could upload huge blobs and just take up space on the google servers. Who knows what will happen 
if you upload a couple hundred gigs of files. They dont disappear, they are just unretrievable afaict. It is a security 
risk in the sense that untrusted data is being persisted *somewhere*.

Upload a couple terabytes, cause a DoS because some hdd in the DC fills up. Who knows.

The only reasonable way to 'exploit' the bug is using youtube as a
"personal storage" uploading non-video files to your own profile: so what?

That would require a way to retrieve the stored data, which - as I
understand - isn't possible here (although the report seems a bit
hard-to-parse). From what I recall, you can just upload a blob of data
and essentially see it disappear.

We do have quite a few services where you can legitimately upload and
share nearly-arbitrary content, though. Google Drive is a good
example.
