Oomis I fail to see what you want from the Yeshiva in question your right that yes a Yeshiva has achrayus and canceling a Purim Mesiba (a majot event)Ithe se would would impress upon people the sense of achrayus the Yeshiva has.
Then again it seems that what you really want is for the Yeshiva to rewrite the Gemora something that any Yeshiva would be unwilling to do.
