The thing is, how does riot know if a org isn't selling out? Imagine that I have an org, make it to champions, and out of nowhere decide to not step up to the slot. But, underneath the table I have an agreement with the players and another org that, they are going to choose for example G2 and I as an org is going to receive an payment underneath. There is no way to know.
And for free agent teams, riot has already disclosed that if a free agent team make it they are free to choose an org.
Here is different because we truly do not know if the org is selling out or no. Guard could possibly, while leaving esports and trying to make a extra money, decide to sell the slot to another org and we do not know.
