Recommend this one too. I normally use an AppleTV for all my TV needs, but I bought a FireTV stick just to install this app and be able to watch YouTube without ads and sponsored content.
You can sideload a YouTube client with integrated sponsorblock on your AppleTV. But this will require apple developer account ($99 per year). Not q perfect solution and cost money but just wanted to say that is an option for people inside Apple ecosystem.
