Good point, and he may be angry at the producers AND Lowry......but the only public interest is Lowry V Trump, not Ailes V his internal staff.
One, of course, is that what you see is real--there is a genuine feud underway.
But the other facet is more obscure and that is that there is a pro-wrestling quality to this feud.
Both Trump and Ailes benefit from the feud. As Trump has admitted many times in his books, ALL publicity--good and bad--is, in the end, good.
I'm not saying that the feud is choreographed (because I do think Fox is for any establishment candidate over Trump), but I do think there is a tongue in cheek quality about this matter.
Over the years, Trump has remained in the daily news in NYC by creating kerfuffles. And folks have always wonder if they were serious or theatrical. Maybe there's a little of both.
