I was expecting this move, since what seemed like plan A (i.e. get companies to pay for team collaboration features) was quite a tough sell in my experience. I've been using Observable for work for quite a while, but generally my colleagues have not been interested in collaborating on any of my notebooks - they tend to consume them, not produce them. In the meantime the completely free model for using it seemed overly generous given that. Hence we've reached plan B. I was hoping for at least a limited number of private notebooks, or at least unlisted notebooks, since that would make it a bit easier to use for prototyping private stuff...
