I wouldn’t be so hopeful, Twitch has pretty much remained unbeaten and the only “ad block” solution I’ve found still gives a 30 second interruption of the stream, it just doesn’t show the ad anymore. It’s why I don’t use the site anymore, even with Twitch Turbo as an option these days.
Boost is still up at the moment but Boost for Lemmy is already up for pre-registration, so I don’t think it’s a hard cutoff or anything.
