No, he didn't say that. That's your twist on it.
Nattering is going around criticising and finding fault and blaming etc. without being asked to. Disparaging remarks made through being asked, usually continually asked, are not the same thing. Reporters and trouble makers love doing this. They know there is some kind of rift and so prod to get a reaction. Childish.
Tohei promoted his way, Osensei promoted his way. Both 99% of the time. 1% they may be found to protest something. Nothing like nattering.
As I said, putting others down in order to promote self or own way was the point made. Deplorable.
As Jason noted in his quote from Tohei - the record of nattering is public, and quite clear.
