The only scary thought is that all these important operations don't have a plan B if prosemirror, a software they don't write, don't own and presumably don't pay, goes away.
Also MIT-licensed software doesn't 'go away' all that easily. If a piano fell on my head tomorrow, interested parties would probably manage to continue development in a fork.
Many of them do pay.
