He probably got fed that idea day in and day out while there.

I have worked for a few different large organizations and have often faced the size excuse for being unorganized and ineffective. I personally feel it is a cop out, and self fulfilling prophesy once it becomes an accepted perspective, because then people stop trying to be better.

I have also worked in big organizations on kick-ass teams who are willing to fight uphill battles against "we are too big to change" attitude. Thats what made them awesome teams.
