If enough people don't like the rules they won't get watched and their stream will fail. However I know of at least 4 relatively successful streamers (they only stream for income) I watch that have that rule in place and the 300+ people watching them at any given time don't have any problem following those rules.

You basically came here wanting confirmation that you were in the right.. but in most peoples eyes you were not only a bad guest, but you're being a tiny bit elitist by getting so incensed over someone not playing like you wanted them to play.
Not just Twitch, but other sites like Mixer as well. Backseat gaming like that on my channel would likely garner you a permaban right off the bat if I hadn't asked for it (I am VERY strict with my rules). Most people respect them. No backseat gaming is the norm on streaming sites. Spoilers are included in backseat gaming for me.
