My guess would be that the problem comes up at about the 12:30 or so mark where the speaker begins pointing out that, Biblically speaking, problems within God's organization have gone all the way up to the top echelon of its human rulers.
To be sure, the speaker is being very accurate, and not at all being direct against the WT leadership. The elders who cut him off would have had to think that thru before deciding to end his talk. Maybe that is why it took a couple of minutes before they acted to stop the talk.
This is typical (from my experience) of how thought processes are interrupted in the KH to prevent or cut off any thoughts that might lead in a direction WT does not want you to go.
When you recognize it for what it is, it is more than a little despicable. Not at all different from how North Korea controls ones thinking processes. And any thoughts that might lean in a wrong direction are typically censored before they can actually get the main point.
