There's different schools of thought about how you deal with what you consider to be an unfair result from the powers that be. At one end, you fight city hall at every opportunity, and create an 'us against them' atmosphere at a club. At the other end, you take your lumps, and focus on the things you can control.
Most coaches these days tend to hold the view that the players (and coaches) should focus on the things they can control. No-one at Freo can control the MRP. If people want to suggest the MRP is biased, or incompetent, or both, that's all well and good. There might even be some truth to it. Fans at every club feel the same way. But at the end of the day, there is nothing that can be done about it. We're stuck with the current members for the rest of the year. You may think that taking it up to them will help us somehow, but it could equally go the other way. There is no way to know. It's out of our control.
Ross wants our players to focus on their actions. Does the MRP panel give Ballas a tough run? Sure. If there are conscious or unconscious biases against Ballas, it's because he has proven himself to be someone who will likely sneak in a cheeky one now and again. As coach, do you want Ballas focusing on how unfairly he has been treated (which is questionable and outside of his control) or on the things he does on the footy field that put himself in a position to be treated harshly. Frankly, he is too important a player for us now to be constantly engaging in that sort of shenanigans.
As shane points out, there is an appeal process. Fyfe was aggrieved at his kicking charge last year, and if memory serves he requested we appeal. We did, and lost him for an extra game. So coming out in support of your player isn't always the best thing (in the short term). Appealing is a long shot, but it seems we have form in supporting the player at their request. That's all you can ask for. It doesn't matter what we think.
As for people being upset Rosich is taking a break, I reckon that is a bit churlish. He's there mostly to manage the commercial operations of the business. The sponsors are locked in, the members are locked in, the stadium deals are locked in, the merch is on the shelf, the players are (mostly) locked in. I'd dare say rounds 6-10 aren't the busiest for the CEO, when the focus is on players.
