Manjrekar and Harsha is well experienced with their commentary and its expected to have different opinions from them. I think the visibility issues will decrease day by day when cricketers will play with pink ball from their academy cricket to local leagues.
The visibility issue or the issue in seeing a pink ball coming at your rather than the white and red balls. If it is simply a color issue it will be sorted out as every player will be facing them for the first time. There is no doubt that Manju was always an over-rated individual. He was a below average player, who somehow found a slot in the playing XI, thanks to his connections. And surprisingly he has now become a regular in the commentary panel, despite his poor language skills and lack of enthusiasm. There is no doubt that Harsha is much better than Manju.
There are some below average players that are sitting in the commentary booth and give out opinions and while they were playing they were not even that good and they like to critic, i have heard Gavaskar giving his opinion when some players show some aggressiveness in the playing field and during his playing days Gavaskar got involved in many fights with players and umpires and even stopped matches and those people come out and criticize, Manjrekar is not even an entertaining commentator and yet he is making a ton of money doing this gig. 
It was a jerk move and what was his issue with Jadeja. There is no doubt that Harsha Bhogle is the better commentator and anyone can voice their opinion and you do not counter that with a dick move
