From live sports not being broadcast due to the broadcaster not having the rights in your area, to live broadcasts being bombarded with advertisements, to leagues deciding against putting a team in a city because it’s not profitable enough even if the sport is popular in the city (see Quebec in the NHL), to rich leagues from the global core stealing all the talent from the rest of the world leaving competitions in the global south worse off. I could go on and on.
The way professional athletes are used and abused for profit is also terrible. There’s inherently some element of danger in sport, whether it’s low impact or full contact, but the profit motive always means safety is a lower priority. The NFL covering up the well known health effects of head injuries is just one example that comes to mind.
