After getting a server with them, I notice they give themselves root access on your machine by storing authorized_keys2 in ~/.ssh (at least on the Ubuntu Server image) and provide their own custom kernel that most likely has vulnerabilities.
They need those keys to help people that manage to lock themselves out of their server. You're free to remove them, but then you're on your own if you mess something up.
You're also free to install whatever kernel you want if you're worried about vulnerabilities in theirs.
