The team feature just totally hosed my reputation. I sent a team invite (because it was implied that this will be needed for Paper) and it's taken over a bunch of our team members' drop boxes, disabled 2FA, and permalinked people's personal files to a corporate-esque group that they can't unsubscribe from.
hey, i believe anyone can leave the team from dropbox.com/team. the team feature in Dropbox, in its current form, is meant to be used for "work" teams. Check out this help article -- https://www.dropbox.com/help/9124
