Like I said - studios care about the optics of success not actual success. Since more advanced third-party viewership trackers have appeared in the US, the streamers have started releasing these “global viewership” figures because they are completely unverifiable and they can sound gigantic - like a manufactured phenomenon (IIRC globally Wish nearly doubled the ‘massive’ global viewership of that Taylor Swift concert according to Disney).
When something’s actually doing well they’ll just put out numbers that line up with a third-parties number or just use a third party’s figure.
