There's no agenda or secret backroom meetings. The referees as a whole suck at their jobs. Just think about how many plays this year have been quick reviewed and overturned without an official review or coach's challenge simply because the booth saw that the refs got it wrong.
And they aren't just missing PI and holding which can be subjective. They are missing full on punches to the face, facemasks, low blocks, leverage, and anything else that is obviously observed and mentioned by whomever happens to be in the broadcast booth.
To have all of this technology and not be allowed to use it is borderline criminal.
