"Agents are entrenched, and they will put up a damn good fight to protect their margins" is how I read this.
Also this is a PR move for Zillow to tell agents that they're on their side.

And more likely that they have something in the pipeline intended to do that exact type of disruption.
Also note that a lot of agents, at least in our area, HATE Zillow. I guess I haven't been to a Realtor conference in a couple years, but there were well-attended talks about "how to keep your property out of Zillow". Some Realtors wanted to work with Zillow, but quite a few were trying to keep Zillow out.
