My recollection is that Eddy Cue got the most critiques, Phil Schiller the least and the rest were in between. Eddy would push back and still get shut down.
When Steve left the last time, it was knives out between these guys with Scott Forstall taking a fall as Tim Cook got ultimatums from everyone including Jony. I imagine loud voices with bad taste are pushing Tim hard. Apple can be an investor darling but Tim has needed to consider an exit and find a strong successor that knows what made Apple great in other ways.
