It depends always on the use case, if the code is open source, and a server is only there to make it perform well then it is a valid use case of softconsensus. Everyone can verify it, and everyone can create their own server with valid data if they wanted to as well as own frontend.

If it is not open source it is more complicated, then the things can be verified but in the end the company can still just stop existing the and the userbase might need years to develop an alternative to run on the past data.

But in the End, smart contracts end up being open source because they are deployed on the blockchain as well. So it don't think its good to compare non-open-source consensus projects with open source smart contracts
