Asmon says his 2nd channel will likely be forced to partner soon because his average viewer count has gotten so high he is now costing twitch a lot of money by not having ads run on the channel.
Partnership isn't a signed contract. It is a benefit they give to a channel.
Twitch is a business, not a democracy. They can say "Your channel will be partnered or it will be banned. Pick." and there is nothing you can do about it.
