They internally call it AI fairness or whatever.
It probably is the case that in this representation entertainment such as WWE and MMA ends up being viewed unfavourably by Google since they are vaguely associated with political powers that want to limit tech censorship, etc.
I think this is happening and it is bad.
Since results are highly personalized one way to fight this would be to install search bias monitoring extensions and statistically proving that results are intentionally biased for censoring porposes(which I think amounts to abuse of market dominance)
To avoid such monitoring Google is going to roll out strong restrictions on allowed browser extensions(linke manifest v3 in the name of privacy) at the same time meta/fb is just banning accounts in order to stop statistocal monitoring of their bias. [1]
Expect more of this unchecked soft censorship as user rights and tech accountability slowly diminish.
