Do your research, dude. What they are doing has nothing to do with putting their own capital
They won't initially join, as they know it will hurt their free raid that they are doing right now across European football.
PSG never joined in 2021, and City were the 'inside traitor' that first left and questionmarks were posed as to their stance in the first place (leaks at the time were telling)
But even if they join, or are forced to follow some years after the ESL formation, seeing that they are being left behind and out of the elite, they will play by the same rules.
In the document published by ESL clubs midweek, there was a clear point in FFP regulations and close monitoring to trace financial ways of cheating
Don't worry, there is no way back
