depends on what you watch. Some people are very into streams and barely watch youtube, so it's not even a comparison. I'm the opposite and can catch maybe one stream live a month.

increase in price always leads to a lower demand. I'm sure they took that into account before the price hike.
Then again, I just use an adblocker for any twitch streams I watch live.
