For me, HIVE and blockchain provides a place to create without the worry of unintentionally supporting an immoral cause. Creating on a centralized platform means that you have some responsibility about the actions and mindsets that the platform takes. Personally, I do not want to have responsibility about the mindsets of Twitter for example, and creating on the Blockchain solves this. I am responsible for my own content, and the platform I create on has no central actions or mindsets, and therefore doesn't cast its own narrative. Because it is decentralized, there's no smoke and mirrors on HIVE (at its core level).
Absolutely! That's a way to ensure your voice is not distorted or censored at the core level and that there isn't the politics of the platform which may become contrary to your own views.
