I get no ads on Twitch, and I currently don’t have Twitch Prime or any subscriptions. I’ve spent maybe 50 bucks on Twitch in the 3-4 year lifespan of my account. I’m running Vivaldi (which uses Chromium) with uBlock Origin, Ghostery (I know), and HTTPS Everywhere, on MacOS. I get ads when I use Twitch, with the same account, on a stock installation of Chrome (which I use as my backup browser for when I don’t want to figure out which extension is breaking a website). So it’s not related to my account, location, etc.
