I'm not against having Simula foot the bill in preparing whatever materials they may need to prepare to aid in the FCC's investigation - I think that's a reasonable cost of doing business, one that ought to scale with the size of the company, no? However, I agree that there may be valuable information you'd rather your competitor not have access to at your expense. Is there instances of, or analogues in other domains, of information relevant to the persecution of one party, belonging to another party, being reviewed in confidence by a third party? Or failing to find a fair solution in terms of that approach, how much can that information be trimmed?
