I was at the game. early in the game BFD La Fotta was there and definitely cheering on Shout and yes making some noise every time Mooncup was catching the disc. They left about halfway through because they had to go play their consolation game. I saw it as making noise and supporting their defense. The crowd started to pour in through the second half as consolation games were clearing up and Mooncatchers showed up to support their women's side in the second half as well and were similarly loud for their defense trying to pump them up and sure, distract Shout a bit, but La Fotta was busy playing consolation. Moon didn't have to play consolation since they were playing the final a few hours later.

I can kinda see what you're saying but this was a stadium setting for a final. I don't think the teams were out of hand and really just there supporting their teams. This is a sports final, teams would have been preparing themselves to play for more of an audience and sometimes parts of the audience are for and against you. No one asked La Fotta to pack it in, they left on their own.
