It depends what he’s the CEO of. For example whether it’s a non-profit, a for-profit, a co-op, etc. It also depends on the licensing of the data. I don’t think this last bit has been tackled by Lemmy yet. Wikipedia has done it quite successfully. If the data is licensed under CC for example, and backups are published, then migration of the whole instance becomes possible like it is for Wikipedia. That would be one hell of a disincentive to fuck around, even if the company is for-profit. Non-profit co-op plus CC-licensed data is probably the most resistant.
