That part is annoying but I generally don't subscribe to channels that overdo it. My remote has a button to skip 10s forward so I keep pressing it until I see sponsored segment is over.

I'd love to be able to use sponsorblock on ATV but I don't see how it could be reasoned that it makes morally ok to not pay Google and content creators for the service they provide (with cash, ad views or otherwise). Video hosting ain't cheap.
