This may sound like a horrible idea, but it can help over time.
I think he should remove his Patreon as a whole because now he's doing goals on Twitch instead of Patreon. So what exactly is the point of pledging on Patreon if barely (or even worse, none) of the goals are being delivered? Ask the king questions are usually answered from the stream chat anyway. For those that want to donate to DSP monthly are gonna have to be subbed to the channel, which is a good thing because he can get better support from Twitch.
This is a great idea! Use YouTube only for reviews such as DSP tries it, etc.
