It's not about "deriving satisfaction" from it. It's about it being considered a sport so it can be aired on sports channels or even have tournaments for it.
I'm talking about people in general though, not professionals. People who wouldn't be good enough to be on TV anyway. And you can have tournaments, competitions, etc. for anything. Society does not consider playing the piano a sport, but there are still plenty of opportunities to test your talent and hard work against others. It seems like people feel better about themselves when they're convinced they play a sport and others don't, and that's something I cannot understand.
