I think lots of people also don’t know how easy it is to migrate all user data between browsers. Also, the added work of changing your phone app is probably too much for the average, comfortable consumer.
During last year, I watched two series (only murders, Andor) and one movie. Disney+ is convenient and I can share the account with some friends. But at some point, it’s literally cheaper to buy the things I watch directly and then also own them. Set up a Plex instance and it’s also easier to share with friends.
