A couple of very well made points however you are coming at this soley from the point of view of Man City. In the hypothetical scenario where Man City are challenging FFP in Switzerland or Brussels or wherever UEFA will say they legislate for hundreds of clubs across Europe, just because Man City are the exemption to the rule it doesn't mean the rule should be changed. They will say that legislation has worked and produce mountains of evidence to prove their point. Man City themselves are evidence of a club competing right at the very top of the game while operating within the FFP parameters for the last few years.
Based on where City are now I don't see them going down that route, I think it will end at CAS win lose or draw.
You are looking at that from a Spurs fans point of view though. City will not settle for a loss that's for sure. They were offered a plea bargain and declined it, that says "fuck you we're innocent" to me, I don't know about you.
Of course UEFA will argue how good FFP has been for European Football, we've had endorsements from Ed Woodward himself, who's totally unbiased and speaks for all of football. The fact is, they took debt out of the equation to suit the cartel clubs, when that would have served the 'hundreds of clubs' better in becoming more financially sustainable. I'm sure you're aware that debt has risen £1.2bn across the continent(£6bn to £7.2bn) since FFP came in, that clubs are still going into administration despite not failing FFP. It's done some good no doubt, but it's clearly flawed, all just to suit the elite.
Sadly I think that since City are financially sustainable and are/will be in a position to attract a new major shirt sponsor, if the verdict is overturned, then City will not set out to destroy FFP.
It could be that City will slowly move away from all UAE sponsors one by one, replacing them with global brands. City will still have one of the highest revenues in world football and so the argument will then become "ah but it was unfair how they got there" from the usual cartel club fans. Which would be ironic, wouldn't it? It's exactly what non-cartel club supporters have been saying about their own clubs and how bringing in rules to stop others repeating their success stories is hypocrisy. That acting like they were never financially doped(Liverpool, even Spurs bought success in the 60s, your own fans admit it), offered uneven TV revenue splits for over a decade, was at least as equally unfair. That creating wealth gaps that never existed in the 90s, out of a sense of entitlement is what really "ruined football".
If City get that point in the paragraph above(0% revenue coming from the UAE), there might be sense within the club that after working so hard, that they should benefit from this same draw bridge in the ways the cartel want to. I'd rather they did challenge FFP though, if that means Everton and the likes benefit so be it. There should be no protectionist or elitist laws in football. Too many people have seen through the lie of FFP, it would need a name change and complete revamp for alot of people to trust in it. Make it about debt, protect clubs from bad owners(leveraged buyouts etc) by all means but there needs to be a new set of rules that actually does what it says on the tin.
Also from the same article you quoted (I read the same thing recently):
The Regulations state that the CFCB shall ensure "
the equal treatment of all licensees" when carrying out its responsibilities.
28 The Joint Statement, referenced above, provides that "
it will be vital to have uniform standards of equal and non-discriminatory treatment of all football clubs".
29The Arrangement for Co-Operation cites transparency as a key factor in the regulatory framework for football.
30Both UEFA and the European institutions make it very clear that transparency and equal treatment are key to fair regulations.
I think they will have a big problem showing that they have not discriminated against Manchester City.
