As somebody who is connected to broadcast, that doesn’t seem right to me - broadcast TV tends to be very control-freak-ish and the higher ups LOVE data, and I really doubt a broadcast exec would willingly chuck out an audience measurement datapoint. The broadcast ad model is that you create shows that have big audiences so you get lots of ad impressions. The decision to remove the dislike button seems more about removing community negativity and/or simplifying moderation, which isn’t really something that I’d expect a TV exec to put a big push on.
