Twitch recently announced a number of new regulations for sponsored content. Many previously tolerated ads are no longer allowed during livestreams.
Advertising and sponsorships make up a large part of Twitch streamers' revenue. If the existing advertising opportunities are eliminated, important advertising partners could possibly jump ship. Kick is one of them, which is now trying to lure creators to it. It's a bold move by Twitch that may drive many big streamers to other platforms. Twitch is already rowing back: On Twitter, the company released a statement apologizing for the "confusion and frustration" caused.
