Entertainment is entertainment. It's subjective to tastes, what entertains some people may not entertain others. I'd rather give every penny I have to a streamer than sit through an episode of the x factor or [insert country name] has talent. As it happens I don't give money to, or in fact watch streamers at all. But the fact they are popular means people enjoy it, and they are free to spend their money and time as they please. Last but by no means least, learn how to -blam!-ing spell before you start patronising people on the internet. "Your too young and nieve"? Kids these days...
