Hive.Blog is not Hive. Hive.Blog is just a frontend (website) allowing you to access content stored in the Hive blockchain. The Hive blockchain itself is a speech free platform. You cannot hide/remove content from the blockchain, Hive.Blog is only preventing it from being displayed on its frontend.
Using a block explorer, you can access and view any hidden posts or comment, your hidden comment for example can be viewed here:
- https://hive.ausbit.dev/hive-139531/@introvertspeaks/re-quochuy-r07lgu
- https://hiveblocks.com/hive-139531/@introvertspeaks/re-quochuy-r07lgu (Hiveblocks is down currently)
If you are a developer or know a developer, you could even create your own frontend that does not hide anything.
So while you could say some Hive frontends are not fully free speech, Hive itself is.
HIVE itself is the blockchain, Hive.Blog (Condenser) initially created by Steemit Inc. was created just to demonstrate what the blockchain can do. If a group of people wanted to create a fully freedom of speech platform using the blockchain, then they could spin up their own frontend using the existing blockchain.
The blockchain is decentralised, never the frontend. Currently none of the frontends are decentralised:
I agree with you, it's far from perfect.
