There's many things in this and stances that needs to be solidified. First off, are these people sports athletes or entertainers, the distinction is very hazy here.
Second, no doubt these media companies are predatory in nature and rules need to be established, but unless they are in breach of what these entertainers/athletes signed up for to begin with, it's a hard case. A case like this can set precedent for how things should be done going forward, but people sign dumb contracts every day without seeking proper consulting.
Third, if these people feel fed up with others taking their revenue for reasons that may not be illegal, shouldn't there also be a revenue split for the gaming companies which content you are directly making money off? There is a huge amount of hypocrisy with this and these "content creators", game creators need as much legal say as content creators when it comes to how original IP is being used. It's dumb how we accept you cannot upload an entire movie with dumb jokes recorded over it, but it's totally fine to do with a linear narratively driven game.
