Pornhub doesn't generate most of their money from subscriptions. It was never their primary business model to do that. It's mostly ad and referral revenue. I also think most tube sites run on thin margins or even at a loss. And like a commenter below mentioned, you can't do recurring payments with bitcoin. It's strictly a push payment, and even if there were a third party or service that could effect a recurring payment model, it would be too risky. A good chunk of porn site revenue comes from rebills to people who forget to cancel their subscription after they've joined at 2am Saturday morning, drunk/high, needing to pound one out before passing out. (This is literally the description of a typical customer a porn studio manager gave me.)
