All the batting coaches and other officials who have worked with Babar ie Gibbs, Hollioake, Yousaf, Wasim Akram etc have confirmed that he sticks to his comfort zone and doesn't listen to advice, suggestions.
In the last few years you have seen a big regression in Babar's batting, his strike rate has dropped, he has become susceptible to all forms of dismissals ie playing away from the body without footwork getting caught behind by the keeper, slips, lbw or bowled bw bat and pad, getting stuck against spinners, getting caught at midwicket, getting caught down the leg side.
Just by looking at him, you can tell he has let himself go big time fitness, diet wise and its had negative repurcussions on his game. Ramiz made him an all powerful unaccountable captain and he abused the power to accomdocate his doosti pyaari Saya buddies and to do away with the fitness, diet culture in the team. It is the captain who ultimately drives the culture and environment in the team. Just look at what Kohli and Rohit have done for India as captains.
The PCB have done the right thing. No one is bigger than the game. I do not buy this argument that who does Babar talk to regarding his flaws, the evidence is there that you can give him the best batting coaches, he won't listen. Also he has now been playing professional cricket for a good ten years now, he should be knowledgeable enough to fix things himself without needing any hand holding.
It's up to Babar Azam now. Does he cry in the media and use his political connections to get back into the team without performances just like how he back stabbed Shaheen to get back the captaincy or does he genuinely put the hard yards in and score so heavily in domestic cricket that the selectors have no choice but to recall him.
