I hate Netflix as much as the next guy but let's not shield our eyes from reality. Their move was actually very successful. A small percentage of people unsubscribed, but that number was dwindled by the number of new subscribers. Netflix basically proved that people for the most part don't care and will subscribe just to keep watching. Of course Disney and others will follow suit after seeing that.
We don't have the metrics yet to see if they stay subscribed. Look at it this way, Lemmy grows and shrinks by leaps and bounds every time reddit does something crazy. Same principle. This also doesn't take into account people wanting to subscribe to finish a show and then unsubscribe afterwards.
So many companies are following the boiling frog philosophy these days because it works.
The general population will consume, consume, consume no matter how bad you make it for them. People don't notice, people don't care. If they do notice, they'll shout at the sky for an hour then go watch the latest Disney movie on Disney+.
