Not everyone is willing to learn.
There is nothing simple about Facebook, Twitter or Pinterest to name but a few, yet people find their way there. They spend their time there and they provide it with content without earning anything from it. The whole time, those platforms are collecting your data and tracking your movement so they can then make a profit from it.
People come to an ecosystem that doesn't track them or profit from them and expect to not have a learning curve. That doesn't make a lot of sense to me.
You can make the blockchain as simple as you want it really. You can use one frontend, choose communities or no communities, and not bother using any tags to earn tokens with. If a person wants to earn Hive they still need to post regularly, comment and engage with others and build a following. And use the wallet.
Or just play a game. There are a lot of people who only play Splinterlands on Hive. They are quite happy to not bother learning anything but the game.
Yes, there can be a lot to learn. A lot of new concepts because they haven't been into crypto before. That is never going to go away. Just like there is a learning curve for someone new to using a computer. The choice is learn or not bother.
