It's hard to fund development without releasing something, and at the same time, releasing it prematurely runs the risk of entrenching undesirable features/behaviors/etc that stifle development of something better.

Releasing it closed source allows them to point to something that justifies further fund raising and allowing them to control the direction of development while getting user feedback.

This isn't some esoteric language where if mojo vanished you'd lose your whole project and have to rewrite it into something else. It's python with some syntax sprinkled on top, so vendor lockin isn't a huge concern.
