My problem is that Dropbox does everything that is highlighted in this post as a reason not to use Google Drive. If anything, the Dropbox TOS reduces clarity by "hiding" that they do these things.
> use, host, store, reproduce
Well yeah, that's what the service is designed to do. Dropbox does all of those things.
> modify, create derivative works
Something as simple as creating a thumbnail of a JPEG is modifying/deriving your files. Dropbox most certainly does that.
> communicate, publish, publicly perform, publicly display and distribute
Again, this allows them to show you your data in multiple ways that exist now or may exist in the future. Again, Dropbox does all of these things too.
I honestly think that Google should have added "We will never sell, give away or allow partners to access your files without permission" to the top of their new TOS. It would clear all of this nonsense up.
