And Dropbox hasn't done anything to any users of the code, as far as I know. What do you think Dropbox is doing to people who poke at the code or use it?
"This is Arash from Dropbox. We removed the project source code from the user’s Dropbox because it enables communications with our servers in a manner that is a violation of our Terms of Service. By our TOS, we reserve the right to terminate the account of users in this case. However, we chose to remove access to the file instead of terminating the account of the user."
I'm questioning whether possessing the file without using it against Dropbox is actually a TOS violation.
