I know if I was hiking the trail in the fall I would love to be able to take a break and watch my favorite football team play. I don't see the big deal. You can still go see, smell, and feel anything you want. In fact, watching it on their phone would be a very minimal distraction to others.
If I am the first to arrive at a shelter in the summer you can guarantee that a baseball game will be on my radio for everyone else to hear. If you don't like it you can move on. If I was not the first, I would ask what the others thought of it. If someone objected then I would plug my headphones in and listen to it that way. Usually the only thing stopping me from having a few drinks and listening to a game at night is dead batteries. It is something that I really enjoy after a long day of hiking.
I certainly don't expect others to get the same enjoyment that I get from this. But if you told me that you don't want to be in the same shelter as someone who is wasting their time listening to a baseball game, you would definitely not like what I had to say to you after this. If the case is that you can't be around someone that gets enjoyment out of something you disagree with, you should probably sleep alone every night.
