If Hive, the blockchain, is a kernel then APIs are the drivers. Most people don't use the kernel alone, they want the whole system that just works
I didn't imply running closed-source software inside an open-source host. I said publishing a closed-source software in an exclusively open-source repository. Big difference and not entirely analogous
Now if you really want to administer an internally governed and controlled community based on common interest on top of a certain Hive application and impose whatever brand of censorship pleases you, it's fine and all up to you as long your censorship is confined, no problem
What's happening here is different. It's not just the local community that you create you're trying to moderate. It's part of the system that allows applications to operate and provide a place for communities to exist. How about you set up your private node? There's no one stopping anyone. You say. True. But how is that any different than spinning up your own server and centrally host everything on your terms?
One of the reasons why people love to publish on free hosted blogging platforms is the relative ease of use. You create an account, write something, and hit publish. Bam! Now if you're going to make their lives difficult by recommending to maintain a private node, it's over. The magic is gone and they'd be more than willing to find a new home where life is simple and not a pain in the ass
