Well given the scenario. I'd push for the simple reason I'm either beat or not. Why give someone a chance to chase you down? It's only a freeroll. Also, you just might get someone to call with their drawing hands anyways. They're also thinking screw it it's only a freeroll.

At a money tourney. I'll try the aggressive approach (3xBB) and fold if reraised. Only to see how much gamble there is at the table.

Just my two cents. Maybe a reason why I only do marginally at MTT's
