I doubt it's actually helping them at all. If anything, they just don't notice, because their business is primarily made up of Dropbox for Business accounts, so even if a paid personal user like me leaves because it's that's so annoying, they're not hurt by it at all. But even then, I rarely use their web interface, so it's not enough to push me away.
