Since the kernel is the most important part of an OS, Infinite's critics believe that it's a security risk to have Dropbox sitting in it. Sam Bowne, an Ethical Hacking teacher at the City College San Francisco, told Motherboard that it's like Dropbox is "proposing to copy the keys to your house, move in and live with you."
