At this point it's understood that Netflix is a service for watching Netflix original content. Anything on top of that is a bonus, and may not be around a month later.
30 Rock wasn't on Netflix anymore, last I'd checked.
Friends is my most watched show on Netflix, but that's because there are 10 seasons with 24 episodes each (i.e. a lot of content) and it's just something that plays in the background while I do other stuff. I wouldn't care too much if it was removed, but I would if they took away Stranger Things, Ozark, Our Earth, The Crown, Altered Carbon, Narcos, Santa Clarita Diet, BoJack Horseman, Queer Eye, all the comedy specials and lots more.
