Frankly, in the beginnings of computing, including in DOS and OS/360, there was often an assumption that all users -- at least all "real" (TSO and development, as opposed to CICS or application) users -- were trusted. There was a lot of your gun, your bullet, your foot. The assumption was that the threat of dismissal was a sufficient limit on misbehavior.
We are seeing a continual plugging of the resulting holes, on this platform and on others.
