One thing I can say is that if they had knew about Masashi's family tragedy, those editors SHOULD not pressure him to finish Naruto and added in their own 2 cents. I may not know if the Japanese experience the same grieving as the Americans or any other Western country that had lost a loved one, but they should had gave him room and time to grief, not taking advantage of the situation. It is still assumption but it sounded like that what was those editors were aiming for. Then we have the other rumor with Road to Ninja itself: Masashi was changing stuff around behind the scenes and someone said majority of the SP staff didn't like what was going on (in my own good, professional wording).
Like I said...a while back after Kishi's dad passed its clear he had some sort of mid life crisis, likely wanting to end the manga so he could spend more time with his family, and the editors pressured him into doing nH because "that's what the fans want."
Bail heard something about Masashi "was going back and forth" with ideas during RtN's production which apparently "pissed" off the SP team. There was a discussion about it in one of the threads here.
You'd have to show me the post because I can't remember exactly what that was. As for going back and forth either that is was for either NS and nH. Or I was talking about The Last and how canon it was.
