They save a lot of costs by deduplicating copies of files, and it makes file renames/moves/shares really easy for them. Therefore, they wouldn't have the incentive to destroy that advantage: That's one of the major scale advantages they get for covering so many users.
I posted this elsewhere in the thread:
That's not true. As is, in a lot of crypto problems, there are powerful workarounds that require a lot of work. See here for one idea: http://news.ycombinator.com/item?id=2461713
Please also see the further discussions. Crypto gives us powerful tools to mitigate several attacks with minimal compromise on functionality. Unfortunately there are legal ways that are more powerful.

That idea doesn't work. It doesn't stop a third-party from seeing who has copies of a file.
