Nope. I'm with the players. It's them that are drawing the views in, not UEFA or whoever - if I was a player I wouldn't allow them to use me to advertise products I took issue with so they could make money off of me.
UEFA can have their product on the table and it won't get moved if the player isn't there, problem solved. Oh, except it doesn't get the exposure because the player doesn't do the press conference.
You may have the cart before the horse. Corporations like Coca-Cola can exist completely separate from football. They don't NEED football. Coca-Cola was immensely successful before football, and if they stopped advertising via football right now, their market share is so established that their profits would see little dip.
As with any of the fortune 500 corps that advertise with the sport, I would imagine.
However, global football, needs media, and with few exceptions, media need advertising dollars.
TV deals help to pay player salaries, like Ronaldo's, and fund parent organizations which fall under FIFA, UEFA...etc.
You see the symbiosis? You see, no sponsors, no media. No media, no massive, state of the art stadiums and multi-million dollar salaries.
Ronaldo would be just another man playing playing a child's game for his share off a 20% cut of gate receipts.
Moral of the story...don't be a prick. Don't bite the hand that LITERALLY feeds you.
Ronaldo is a prick.
