Re: I don't get the fuss
In which case, sir, you are an idiot. There is a massive difference between hardware kexts and a data copy agent. Even if they "hacked the client", that's a user process, not a kernel one.
Currently, Dropbox has access to one folder on my system. The only non-trival item in that folder is an encrypted .dmg, to which Dropbox does not and will not have the key.
Anyone who gives an online syncing service "access to everything of worth on my computer" deserves everything they get.
