Definitely critical for Apple TV+ if they want to compete with Netflix and Youtube. Though both of those together account for a quarter of the total bandwidth on internet, I'm not sure if Apple TV+ is anywhere close to that yet, but long term planning here.
Unless there is some kind of limitation for the 1 year free AppleTV+ offer (when buying a new device) it is a terrible service and not even a competitor to Netflix. The prices for movies are abnormal - Predator (a 23 year old movie) is 4.99EUR for rent. For comparison a small market (<2mil people) local streaming service offers the same movie for rent for 1.90EUR.
