I think the question is the phrase "crying for chinam". My suspicion is it's not "you cried about something unimportant", rather it's "you cried when there was every reason not to."
G-d had promised them they'd enter the land, and here they were crying "oh boo hoo we won't enter the land", there was no reason for them to be sad.
Whereas if my favorite team loses, well I feel upset. That's not a sign of diminished faith of any sort, G-d hadn't promised me my team would win.
There's likely some measure of good sense of proportion, how upset should a sports game make me (and how much should(n't) it allow me to reduce my normal performance of service to G-d), but I think applying the comment from the Spies is quite extreme.
Note the conversation between G-d and Jonah at the end of his book; Jonah's upset is a teaching moment, not a cause for punishment:
"Jonah, are you really that upset over a silly gourd?"
"Yes G-d, so upset I wish I was dead."
Ah-hah! Now you understand why I don't want the metropolis of Ninveh to die.
