It’s stupid and anti-user.
But why (from their perspective)?
They don't make their money from metadata, they make it from content. Every piece of real monkey-making content is going to get a torrent regardless of if it's protected behind a captcha.
Edit: I have some sympathy for this. Engagement is much harder to measure than customer satisfaction. They are looking for the keys under the light because they cannot see anywhere else.
Why be reasonable when you can be unreasonable and make more money.
It makes very little sense to me. Surely WBD wants people to easily find WBD content to watch, and easily be able to pay them to watch it.
I know Netflix has been a holdout (the only one), and it is quite a stupid long term decision in my opinion, but I would not have thought Apple pays WBD, Paramount, Comcast, Disney, Starz, etc to be able to list their purchase-able media in Apple’s TV app.
So it has a real login and, presumably, access to some api from the streamer. But a smaller company that didn’t pay for access could also just login as my accounts and scrape info.
its not strictly required, as in most cases you could just save cookies or similar locally, but weaker login systems are preferred.
