Dropbox Smart Sync is a joke. The whole purpose of Smart Sync = Dropbox. But you make people pay for premium to "unlock it". Dropbox without Smart Sync is ultimately a virus that infects your computer with files I never asked for, that were shared with me. Just give your free users 2GB WITH SmartSync. Jesus Christ. Else what the hell is the point in Dropbox? It's more like a Trojan Horse that dumps a load of files onto your computer without ever asking you to.
