I don't believe the paywall model is going to go away. Content creators have to earn a living and it takes a long time to build a true, loyal following on Hive, a large enough following that you can earn a living from your "free" content. But is it really free? You have to pay with Resource Credits to be active on the blockchain.
Hive is good, but it isn't perfect. Tried-and-true business models won't disappear. They may be transformed by Web3, but that's about all we can ask.
