That is the sort of bullshit that I always call bluffs on. Worse case scenario you get someone all huffy and upset that their rule has been ignored (making them feel unimportant, as they should), and you give them a "whoops, too bad."
Nothing at that talk, but you may not be on the invite list for next time. Microsoft's invite list for TechEd is notoriously political. The leader for each track (an MS employee) picks the session list.
To give an extreme example, one of my submissions was called something like "Fixing Slow SQL Servers." I was told, "At TechEd, there are no slow SQL Servers." It was changed to Building the Fastest SQL Servers. (sigh)
IMHO, life is too short to donate time to people who are going to treat you like a child.
I just created a list of conferences to never attend too.
I live in the real world.
99.9% of the time when you call peoples' bluff on stupid shit like pant color at a talk, nobody cares. Most people who demand that sort of thing have better things to be worrying about.
