Yes, it does. Presumably it's to force "engagement" - making you jump through hoops to get your free forma or whatever, click this after watching that. Honestly, having the stream on in the background was borderline, having to tab out and interact with it might just piss me off enough not to bother. We'll have to wait and see how obnoxious it is, I suppose. I have a very low tolerance for adverts, too. They're like Kryptonite to me; that would be an instant nope if they are part of these Twitch changes.
