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.
Looking at Twitter/X, this won't be the final nail. People stick to the platforms they're on as long as it doesn't directly Negative impacts them too much.
