A solution could be to make it more difficult for the authorities to detect them (resource-wise). The software should be open source and allow users to send and receive peer-to-peer encrypted messages and files. To lower the uniqueness of the network fingerprint, they could mix with the use of tor and conventional networks in addition to the P2P technology to secure more and make it almost impossible to be blocked unless they cut the internet completely which is almost impossible in modern society.

A mesh network is indeed a better solution against censorship, with the right pieces of equipment, you can create a mesh network and not use the internet at all, something similar to when protestors in Hong-kong used Bridgefy (Bluetooth/Wifi waves)to communicate. Radio waves are also a good solution but require other people to have the right equipment too. Opting for these solutions will definitely require infrastructure (very small one) that the state can easily detect and trace and destroy, something similar to the technology used in ARM (Anti-radiation missile). Or they can just use jammers to stop you from sending or receiving signals to or from a specific area.

We can really conclude at the end that:

Any freedom of speech we exercise is at the pleasure of the owners of the ISPs.

At least now!

Regarding steemit and steem in general, it is well known that humans usually don't want to change their thinking/ways unless they are at the brink of extinction. Maybe something good will come out of this once they learn that true decentralization is built on immutability and that the law of thermodynamics also applies to people (theoretically speaking). If you are just sitting there chilling not doing what's right, the day will come when you will have to pay for it, the hard way.
