What if I buy a copyrighted book or document and store a copy of it on Google.

Do I then no longer own the book that I paid for? And does google own it then for free?

That sounds like forced sharing with a company. I don't mind sharing, I think sharing is a good thing, it's one of the first things my parents taught me. Though today things seem a bit twisted.

Maybe such a TOS would be great for file sharing websites, once you upload a file under such a condition then the site becomes co-owner and may share it with common fiends

Yes, I'm getting creative now... I mean If google can do this, then piratebay and friends could take it one step further, and perfectly legal. Hey I don't mind if Google could do this IF and a big IF other sites also may do this. Then it is up to the user what files to store in a cloud.

Maybe Google should make 2 separate drives, a Private drive and a Shared drive?

Ok, that last one was far fetched.

Sure I drifted a bit off, but I hope my thoughts inspired someone.
