A foundation is one idea. But I quite like a viral clause in your will. So, to inherit, your heir needs to (a) maintain your digital legacy and (b) put an equivalent clause in their will, and so on. Maybe it depends on the value of the inheritance but it might be a way to secure a few generations.
Then you could also stipulate that they should do anything they can to use the resources of their time to further secure the digital legacy. You could also make the responsibility always joint and several across all children / heirs.
