Has everything to do with it. Without television viewers, there would be no advertising revenue, and probbly no sport, tbh. Or at least it would have very limited appeal, like minor motor racing events. And teams would be on a teeny tiny fraction of the budgets they’re on now.
So, it’s a form of entertainment. Without an audience, it would just be a bunch of enthusiasts getting together on a Sunday for a bit of car racing. Nothing more.
Which means those who ultimately pay for the entertainment have the right to opinions. Regardless of their involvement in or knowledge of the sport.
Professional sports woon’t exist without people sat in front of tellies watching them. Without blokes in pubs shouting at players on a screen, those players would be playing in the local park, paying subs and having ‘normal’ full-time jobs.
