43% of MLB players are either Hispanic (32%), Black (8%) or Asian (3%). Their representation at the top executive positions (GM, President, Owner)? A small fraction of this. The Selig Rule memo was released during the last millennium, on April 14, 1999.
But yeah you are correct, executives such as Kenny Williams, Theo Epstein and others in the industry who recognize and seek to change this disparity are wrong. Not that I expect someone who posted your drivel to actually comprehend and/or accept these statements.
PS - Your weak-ass Basketball/Football participation theory doesn't hold water.
NFL - There are the same number of Black head coaches as in 2003 (the year the Rooney Rule was implemented), and one General Manager (Chris Grier).
NBA - Until 2017, there were more racist NBA owners (at least two now known - Sterling, Sarver) than NBA Presidents (one - Doc Rivers, who sadly had to work for Sterling), and only three GMs (Dell Demps, Steve Mills and Masai Ujiri). The level of black participation over the 70 years prior had zero impact on who the owners hired or, more accurately, did not / refused to hire. It took an actual commitment by ownership, the people with final say with these decisions, to begin making clear and widespread changes to how their league was run.
It's clear MLB and NFL owners collectively have a long way to go, two plus decades after issuing their respective "rules", to begin to make an actual difference.
