Here's Football Economics 101 in a nutshell for those who are "fighting for justice" in the name of small clubs.
Top clubs, such as RM, MU, Juventus, take huge risk and invest a lot of money each year. Their expenses grow much faster than revenue because the entire system is managed by slow, obsolete, and corrupt structures such as UEFA.
All of those small clubs people are suddenly concerned about have been beneficiaries of this system for decades, and yet failed to outgrow their little pants because they were more than comfortable with the risk to return ratio they were granted by top clubs. They were making money they were satisfied with, while big clubs increased their debts and went all in. Yeah, that was so fair

.
Everyone's beloved Atalanta get money from those who invested them, i.e. big clubs, and don't risk much. And yet they want to have a chance to grab the big prize which is that big not thanks to them but thanks to big clubs that invested billions in this industry. And now they are shitting on big clubs who quite rightfully rejected them.
All of those small clubs and their advocates either are hypocrites or just haven't figured out how this complex system really works yet.
