Leaving aside the past and what happened to Steemit right now I confess that I'm not afraid that Hive will end, simply because I see it as stable and I think it's a project that will have many developments that will keep it growing.
As it grows, the system will be found to maintain the ecosystem as it is at the moment ... at the moment the concern that I believe we must all have is to spread the use of Hive and make people understand how it works and what is 'and behind.
As I said, the beauty here is that we are all responsible in some way for the life and growth of this fantastic ecosystem!
