I know multiple people which complained about it and made them unsubscribe (none from the USA, so these topics are neither interesting nor on topic for any of us)
It was definitely a contributing factory that's for sure.
The number of people who care about this kind of stuff is very low. Most people just want to watch movies, laugh, cry. They don’t even know about the culture war. That’s only relevant in the bubble of malcontent that is mostly made up of twitter users.
I think more people care than you think, but they might not realize that identity politics (or politics in general) are what’s making a show worse. Star Trek: Picard’s latest season was terrible in many ways, but it seemed like the entire plot was made just so the show runners could say “ICE bad. Global Warming scary.”
That’s all well and dandy if you have an actual point to make, but they didn’t. There was no nuance because in their minds any deviation from those political beliefs are evil.
For it to really be that big of a factor you’d have to explain a) why it hasn’t been a factor before now (did Netflix suddenly become “woke” this quarter? Doubtful) and b) why haven’t other streamers like Disney+ and HBO Max had similar declines? Are they less woke? By what quantifiable measure? (e.g. Disney has warnings at the start of old movies about how racist they are, it was a whole controversy a few months ago)
