What governance models would prevent this kind of coup?

Ever since two beloved co-ops (PCC, REI) were privatized, I've been eager to learn about more durable, resilent models.

Are there case studies of other orgs to study?

Chick-fil-a, Elon Musk inc. immediately come to mind. Just keep it in private hands, the grubby profit minded masses don’t belong in some enterprises, non-profit or not.

The catholic church is an old organization.

The goal of the institution is to objectify those who command its hierarchy. It's assumed to be possible to do. And in this assumption, we are led to be hopeful for an enduring service.

I fear that such an "objectification" would change the mandate of Wikipedia as soon as some subjects are installed.

> Stallman's concept specifically included the idea that no central organization should control editing.

Can you imagine that I have the feeling that some people might have a problem with that and see it differently and explicitly like to go back to old times of the classical encyclopedia?

Of course. These are ostensible goals. The goals don't have to be realized, in order for the hope to appear.
