hi @bradleyarrow, there is lots of things happening on hive and around it.
I don't think leo is moving away from hive. They are more in the limelight as so many things are happening wleo, frontend, light weight signups and so on.
As for the hack, i have no idea whether it's true. If that happen, then i am sure it will be dealt with. In the digital world, hacks do happen. But if you learn and secure the loops it will prosper

Keep doing what you are doing, and things will happen

all the best and take care
