I don't mean to be rude but you are way off course about who/why people watch Twitch streams. Sure some of the Twitch viewerbase fits your description but plenty of people will tune in for a short period of time. ESPECIALLY people who don't have a lot of time because it can satisfy people's video game urges without actual investing tons of time in playing.
There is a difference between "sensationalist" and using a term that the general public knows. Wi-Fi means something to the average person, whereas "radio waves in the 2.4GHz band" sounds like some obscure thing that doesn't apply to daily life.
