Nobody even cares if they are actually guilty or not, from the look of it. All rival fans just want them punished. It's now a case of guilty until proven innocent. 
Even if they are found not guilty, people are still going to believe what they want to believe. What is in everybody's head is that they are guilty; there is nothing you can tell them.
When you look at the charges, most of them are not that serious to warrant being relegated as people want, actually. Fines, point deduction, and transfer bans are the worst-case scenarios.
Failure to provide accurate financial information
Inaccurate details for player and manager payments
Failure to comply with UEFA's FFP regulations
Failure to cooperate with the Premier League's investigations
I'm not saying they are innocent of all charges, but it's difficult to see how they can be guilty of all, and these are not as serious charges as people make them seem. They are things that many other clubs have been fined for. Or is it the fact that City became successful with oil money?
