thread we have Empire magazine revealing Harrison was an "ex-Starfleet employee" with a quote from Abrams saying Harrison was "within Starfleet and has turned against the organization."
The original plot sumary
from Paramount (the infamous "detonate the fleet" one) says the Enterprise crew must stop an "unstoppable force of terror from within their own organization."
The only wiggle room we have here is that we don't know for sure Harrison is/was a Starfleet officer. But that's beside the point. Tom's
original comment was that we know Harrison is working for Starfleet, and by now we have enough evidence to say that yes, he was indeed working for Starfleet in some way.
"Ex-Starfleet Employee" and "Working for Starfleet" would seem to be at least a tad contradictory.
As to the plot summary, they often utilize misleading hype and hyperbole in place of any kind of useful information. Like Rick Polito's now classic "Wizard of Oz" synopsis that read: "Transported to a surreal landscape, a young girl kills the first person she meets and then teams up with three strangers to kill again".
