Here's what just happened:
I was scrolling through my "Followning" feed, and was focusing on a streamer to whom I had never actively tuned into before. I was following this streamer most likely because a streamer I enjoy and subscribe to raided and suggested I follow. Which I generally do, because that's how we build community.
When I attempted to tune in to this suggested streamer, I was greeted by pre-rolls. And a LIST of how many more pre-rolls to come. "Oh heck that!" Said me, "I'll go tune into someone I'm already subscribed to!"
Examine that carefully, Twitch folks. A double loss for you. I not only tuned out of your pre-rolls, I also tuned out of a possible new subscription. I might have subscribed to this new streamer. Instead I went back to my same-olds.
